Help identifying these, breed and gender

[Jensfunfarm]

I bought 6 barred rock pullets from the feed store then took my chances with a mix of 8 chicks from a local farmer. I'm afraid 6 or 7 of the 8 are roosters. Since I'm new to this, help identifying all my birds would be great but I'm really unsure when it comes to these two.
