Question
I have owned three dogs, L, R, and C. Here is their development in chronological order.
L is our first, male, neutered dog; born in 2000, we've had him since 2002 and he is still alive as of this posting. He shivers a lot, and was nervous coming out of his crate for weeks after we first got him. He loved to live under the bed. Eventually, he lives on top of the bed and buries himself, but he also makes his way down, eats, goes outside, and sometimes relaxes. He is very attached to my wife, going so far as to want to be in the shower with her; we used to have to lock the bathroom door to prevent wet dog every morning, until we got a shower with a sliding door. He seems to have wised up about these things and simply lays down on the rug and waits. L does not play with toys unless no one is looking. L would not eat unless no one was looking. L acts very submissive to my wife, flipping over for her and somewhat friendly (but also very vocal with barks) when she is home, but is a different, quiet dog when she is not around.
R is our second, male, neutered dog; born in 2001, we got him in 2003 or 2004 as a companion to L to help get L out of his shell. He passed away 3 years ago. R was a foodie and would eat until he burst if we let him (he had Cushing's Disease). R could be very aggressive in play, and loved to tug on rope and chase and catch frisbees. R would try to steal L's food (and our food). L would growl and chase R away from his food. Sometimes R didn't care what L thought, but other times he deferred to L. To get L to eat, instead of waiting for night time, we would bring R into the room, then L would gobble his food down. L and R played together a lot and relaxed against each other at times. It was rare, but occasionally L and R would fight, mostly over treats (which R would steal from L and hoard; we chalked that up to his hunger disease), and they each had nips in their ears from the other having bitten down. R was a larger sized dog than L. R was extremely attached to me and would follow my every command; he acted depressed when I was not around, but would still participate in play. He came when I called for him and tried to be with me whenever he could.
C is our third, female, spayed dog and is also alive at this time. We suspect she was born in 2008, and we got her in 2012 as a companion to L after R passed. She grooms L on the face constantly, and L licks her mouth at times and sniffs her. There has been a rare mounting attempts from L. They lay down next to each other and sleep together in a basket, not unlike how L and R would. She is the same size as R was. Now that L is older, he eats his food without prompting; something he learned during the his time with R. L will now try to steal C's food. If C sees L stealing her food, she rushes over, shoves L out of the way with a growl, and eats her food. She occasionally takes from L's bowl, but only when he isn't around. Like R, C is attached to me and waits at the door for me to come home; she dances like crazy when I arrive. She seems mopey when I am not home, in the same fashion that L is mopey when my wife is not home. She comes when I call for her and tries to be with me whenever she can.
Is (was) there an alpha dog here, and what could be used to identify the alpha? Is it L or C? Was R an alpha? Perhaps myself or my wife?
Answer
This is probably not a direct answer to your question, although I hope it will provide some elements. I try to first give some info about the "dominance theory", and then try to answer your question more precisely.
Dominance
The "dominance" theory is overused in the canine literature and, in fact quite misused. The theory derives from observations of wolves 30 years ago. From these observations it was concluded that wolves have social structures based on dominant individuals (the alpha male and the alpha female) ruling over the group with frequent aggressions. On the other hand "submissive" individuals were trying to avoid conflicts with the alphas and they display submissive behaviours.
That theory was, at first, not contested and immediately applied to dogs.
Now, in 2014, that theory has been disputed for 30 years, discussed at length in the literature, and a majority of behaviourists now consider it as useless, at best, or even as plain wrong (references to follow).
Trying to summarise what I read from different sources, here are the key arguments:
dogs are not wolves. Wolves are their primary ancestor. However, both had plenty of time (> 10 000 years based on the more conservative sources) to evolve separately. Additionally, dogs interacted socially with humans and these skills were "selected"
the observations of captive wolves led to many conclusions that are different if one observes wild packs of wolves, where individuals are free to leave the group (which is a key factor why the aggressive behaviours are less frequent in wild packs)
more recent observations of wild wolves' packs tell another story about the structure of the pack: usually a breeding pair raising puppies, with the litters from the previous year(s) sticking with the group
the theory was extended to cover dog-human interactions. The observations of wolves should not play any role here
one could learn much more on dogs by observing actual dogs in appropriate social groups (e.g. many dogs' households, "pack" of feral dogs, village dogs, etc.)
dogs are often neutered. Reproductive behaviours are key elements in packs of wild wolves
If this evidence shakes the foundations of the usual "dominance"/"alpha male" theory, then what kind of social construct can we use to describe the behaviours of our dogs when they interact together?
I mention here three key elements, mainly from Ref. 3:
Resource Holding Potential (RHP): it doesn't require a previous hierarchy to be established, the outcome of an interaction is based on the subjective value that each dog assign to a given resource, for example in territorial disputes. Of course this will vary between dogs and doesn't predict a linear hierarchy to be established.
The idea of subjective/perceived value of a resource seems to apply particularly well to domestic dogs. From that we could say "this dog is dominant over food": the dog puts a large value to the "food resource" and another dog can recognise that and show appeasement behaviours to stop the escalation of the encounter
Associative learning: dogs learn at each encounter what is successful and what is not so the following responses are also based on that. Additionally the physical and emotional context in which the first encounter was made strongly influences the next ones.

Application to L, R and C
I won't comment the dog-human interactions, but on the dog-dog interactions.
From your description of L, and based on what I wrote above, there is no point trying to say that he was dominant or submissive. First thing is that you apparently had him when he was 2 years old. That means that some of his behaviour was actually learned from his previous experience. Especially the "eat only when alone" part.
Your description of R seems to indicate that he really values food, while L might not value it as much. That can explain the behaviour around stealing food, growling, etc. If you consider the "dominance in resources" based on the subjective value that each of them give to the food, you explain the outcome of the initial interactions around food. Then the dogs are both learning what works and what doesn't. You can reach a steady state where both dogs are OK with the interaction because it meets their expectations to get their food and they learned not to escalate too much. So the fights would not be an attempt to set a new hierarchy but rather occasional mismatches between the expectations of the two dogs. One would want the treats more than what the other one expected from previous interactions, and they could start a fight.
In your description of C you actually mention the learned behaviour of L around food.
So you seem to have pretty well0balanced dogs (from the interactions they have with you), it is pointless to try to identify an alpha (see the discussion on dominance), as the interactions between your dogs is regulated by the subjective values they assign to resources and learned behaviour.
