The first photo looks possibly female, the tail angle is weird. But the last 3 photos are definitely male. It's hard to say without any size reference but they might be around 3 months old or so. And I can't really speculate on locale until the male gets more colors. Might be an Ambilobe or something else, right now there's not much to go on. Ask us again in a few months, when his colors are more developed.
Were you given any info when you bought them? What locale did the breeder say they were, or did they not provide any details?
