UPDATE 1-30-2015
Queen 1: This colony has slightly rebounded since my last update. They are at 11 workers and some brood and are still in their test tube set up. I plan on improving upon this set up in the near future so they can have more 'freedom' and I don't have to worry about their escape.
Queen 2: Undoubtedly, this colony is doing the worst. This queen is down to just 1 worker with a small, unhealthy looking pile of eggs. I'm not sure as to what to do to try and save them. Last night I fed them 2 freshly killed fruit flies so hopefully the worker is able to take on the task of single handedly restoring the queen before it dies. If it does not, I'm afraid this colony is a goner.
Queen 3: This colony has moved into a Tarheel Ants' Haven which I had purchased last month (http://tarheelants.c...aria/haven.html). They are probably still sitting around 20-25+ workers and are doing well in their new environment. There is some mold growing in one of the chambers thanks to me overfeeding them egg yolk and then forgetting to remove it within an hour. At the moment, it's growth doesn't seem too bad and it hasn't caused any problems for the ants, yet. I'm at a loss as to how I'd remove it though. It's not easily accessible plus I'd have to relocate the entire colony if I even wanted to begin trying to remove it. I'm keeping an eye on it though.
Queen 4: These have also been moved into a THA Haven. Their population has to be at 30+ workers now. I fed them 6 fruit flies last night and they caught them all within an hour and a half. No mold issues with these girls, thankfully.

I'm not sure if this species' dietary needs change as the population grows but to this point they don't need much variety. As I've noted before, it's just protein and water. They've had nothing but fruit flies (one night of egg yolk) for the past 3-4 weeks and don't seem to be tiring of them.
