Floppy comb is fine. It's actually required in some breeds in fact. Leghorn hens often have large and floppy combs, that is what you are seeing on your brown leghorn hen. Brown leghorn roosters would look exactly like your little mean roo, but much bigger with a bigger tail with more of the curvy tail feathers.
The little rooster is a young Old English bantam rooster. Phoenix roosters are supposed to have more of the curvy tail feathers that are much longer than he has. Do be careful, as roosters that attack strongly tend not to stop attacking, ever. If you have small kids, might be best to get rid of him- despite the small size, there is some potential for real injury- scratching eyes/face or scaring a toddler into running into something by accident for example. His eye looks odd in one picture because you happened to catch their third eyelid in action- birds have a third eyelid that is mostly transparent.. this is normal.
I agree with chickenwatcher on most- would add in 11 on the right side is a cochin rooster, 2 brown lehorn hens on left side. The really dark hens in first pic look like either mixes or one of those 'sex link' cross.
Looks like you lucked out on getting mostly hens, appears there's only 2 roosters in there(the little mean one and the partrdge cochin roo) and also appears most are young birds.
