The feather legged one is a light Brahma, and I suspect most of the white ones are the same. The two buff ones look like buff Orpingtons. Would need individual pictures of the rest to tell, but I don't think there are any Ameraucanas in that bunch.
Not seeing any Easter Eggers or "Americanas" in that bunch. The white ones with feathered feet appear to be Light Brahmas. The buffs ones are likely Buff Orpingtons.
