New to chickens, but the first looks like our barr rock chick, the brown striped ones are wyandottes (through we were told our our chickmunk chick that looked exactly like yours was wyandotte at the store, through now her legs have turned olive-colored which I think means that she is actually going to be Ameraucana/Araucana AKA Easter Egger). I'm pretty sure the spotted ones in the last photo are wyandottes though. I don't know of any of the others.
