Oh, never mind. I listed what I thought they were in order of the pictures, but I see now that the third pictures cannot be an Easter egger. It has orange feet. EE's will have green feet. I'm not sure what it is anymore. Brown leghorn?
Good luck IDing them.
You're safe. You got laying breeds. I want to say Barred Rock (BR), something else:golden sexlink?, and an easter egger (EE). Give it a few more weeks before you decide male vs female on these.
