Got these little ones from the "assorted Bantam" bin at TSC what are they? Also sex?

There were two that I thought were the same but when I looked again one has feathered legs and one doesn't. I didn't expect the face tufts that have shown up either. Anyone know what they are? Also they were straight run so if you can tell my boys or girls that would be cool!

Can you label the pictures (with names or numerical or alphabetical). I think I see possible d'Uccles, Sebright, Brahma, or Cochin. To young to sex, need to be at least 6 weeks old but bantams are harder then normal sized birds.

 

[SunHwaKwon]

1. d'Uccle
2. Sebright
3. booted bantam/muffless d'Uccle or possibly a dark brahma or a cochin of uncertain color (can you post a pic of its back from above?)
4. to be determined
