I could be wrong... but I think the last one looks like it could be an EE. And the first one maybe a black astralop. I had some chicks that looked the same as yours. The middle one not so sure? Hope this helps
I haven't had experience with all the breeds mentioned, but the last one looks like an Easter Egger. I love the chipmunk colored chicks as they lay beautiful blue eggs. The white EE's I've had lay olive colored eggs. The pictures below are all EE's.
