They are as different as different can be (2 are so different I M not entirely sure they are the same species)
All 3 are only 1-2" long each (NVL)
I would guess them to be a month or two old. My new ones at about 3 weeks are probably only 2 1/2" long now. They are still mostly brown with a bit of green starting to show around the cheeks. I have to tell you that A. capra vary so much that some are even overall and totally unpaterned while others have real nice scallops or waves of pattern full body length with a variety of shades and colors overall. At this stage, having never seen a hatchling armata, crucigera or lepidogaster, I don't think you could really distinguish species. Once they have a good start at developing their horns you will see what is pretty much the pattern they will have as adults and should be able to count the horns. At that time you should be able to form an eduated guess at which species they are.
#1 - M - 'spike', is mostly brown, thin, and looks a bit dehydrated. Has his hornes on the crest coming in, no mark on the occipit to indicate horns, he has more spines than the other two, and has very promanent Hip bones. No color I can find to his Dewlap, and he is mostly Brown dark and light, very little green or blue to him at all. I worry about him most, he is least active of the 3
I would also worry about this one. He is still a bit small to be force feeding but is you have to it would be better than watching his demise. Give him a day or two to settle in with minimal disturbances. I would try to give him soaks if he isn't using the water on his own. If he doesn't start to eat by day 3 I would start feeding him to see what happens. I think I would start with a mix of pediolyte, strained lamb, and vitamins. If you prefer you could try boost or ensure.
#2 - F - "Lady Belle", is mostly blueish green, with Brown highlights and edges, very soft rounded face (not pulled out like Erowens and Spikes but pugged up like a disney version) no noted spotting or speckling to her hide, color is consistant over all and no sign of dehydration. She has the faintest hint of Horns on her crest, and 2 spots on her occipit that may be horns coming in. 1 problem, she has one of those white dry lumps that I saw on the Store animal I named Aragorn. It does not seem to hurt her. Her belly is puffy and soft, so I worry about possible worms. I just get the impression that she is female, I do not know why
I would also be concerned about parasites but if she is eating well she may just be well fed. I have seen babies at this stage gorge themselves and they will look and feel a bit puffy for a day or two. As long as she is passing stools and is eating she sounds good. I have seen on several of my capra a bit of a raised spot where I would think a horn would be on the armatas but it is just that, a raised, highly keeled scale. I am not saying that that is what this is on Lady Belle but if it doesn't turn out to be horns I wouldn't be surprised either. My bet is that these were all from females imported together and they were probably all the same species. If not, then you will be one of the luck owners of something other than capra! 
#3 - M/F? - "Tracker" has both green and brown, in that scaled pattern Joe and I were discussing the other night in AOL. He seems to have the start of horns on his crest, but again I do not see anything on his occipit. He, I do not worry about, he has eaten a mealy worm (this morning) and was profiling (complete with orange tinted Dewlap) through the glass at them last night (looked like he was trying to eat them through the glass of the Custard dish I M using to feed them) He is most likely to be the one hiding in the fake plant foliage, and does not want to be picked up. His belly is soft, but not as big as Lady Belles is, and he shows no sign of dehydration, but may be in early head shed
Sounds great. I think you have a good start on two of the three. Spike is an example of my reasoning in not selling them before 4-6 months. I hate seeing animals sold to young to be certain that they are well established. So many breeders will sell baby leos at 2 weeks and so many of them die that it breaks my heart. There's a boy in town here who really wants a reptile. He has tried iguana and started with a cute little baby. It didn't last a long but long enough to outlive the guarantee. Then he got a leo from LLL Reptiles. It looked terrible when he brought it to me for my opinion. It looked totally imaciated and couldn't have been more than 3 weeks old. The tail couldn't have been thinner and it's body was only slightly thicker than the tail. The guarantee was 3 days and he lived 5. I think the parents have given up on him having a reptile and to me that is really sad. This is a boy, 11 yrs old, who works to earn what he wants. He saved him money, called LLL and placed the order himself, and really tried to make this work. His parents are behind him 110%. It just breaks my heart and then we deal with the post below where the kid's parents just don't care! That's life! 
I can't think of anything else you should ask. Do make sure you use suppliments, vits once a week and Calcium once a week, to make sure they grow well. I think we really need to think preventitive when it comes to bone disorders.
Good luck, post pics 
and keep posting. It's nice to see new posts here.
