I agree, roosters for the first three, bottom is a hen. The roosters are some sort of non-standard Cochins (they do have single combs, right?), colors are Blue (with red leakage), Splash (also red leakage), and a some sort of cross (I see trace amount of feathers on the legs so I assume this third guy is also mixed with a Cochin). The hen is mille fleur in coloring, not sure what breed she is.
All of these birds look like someone's projects as they don't look purebred but do have fairly nice coloring.
