Rooster?? Bantams???

I think the last photo is the rooster, but I am not sure. And I don’t have much experience with Cochins but the frizzly one looks like a Cochin, how old are they?

I think they are about 5-6 weeks old.

I have no idea about the barred rock, but looks like you've got (in order of pics) a red cochin pullet, a red frizzle cochin pullet, and a red cochin cockrell

Thank you!
