You have easter eggers (the larger ones with pea combs and puffy cheeks), the two white ones and the smaller black rooster appear to be mixes, and the fuzzy one is a silkie mix. The chicken in picture #4 is an easter egger rooster. I can tell for sure that he's a he because of the splashes of red on the wings, only roosters have that. I agree with you that one of the white ones, the small black one, and the big black one in pic #4 are roosters. Your coop is coming together very nicely! It looks very well built,
