You have roosters. For sure the bottom link is a roo.
How old are they? If you have a better picture of the first one, that would be great, so we can see its back feathers

The bottom link looks like my rooster! ( black laced or golden laced Wyandotte)

One looks like a Dark Cornish, and agree the other looks like a Black laced golden Wyandotte!
