The one in the 8th picture is a golden seabright.
The 3 in the last picture are golden comets.
I agree with Roosters110, the white and brown roo looks like a sex-link
The one above the sex-link roo looks like a dorking from what I can see..
The little brown one in the first few pics is a little hard to tell, can you get a side view maybe?
The bantam rooster is a serama, the buff bantam is a game mix, the gray one is an old English game bantam, and the last one is a sebright. The other rooster is a red sex link (also called golden comet, cinnamon queen, red star, etc) and the hen in the last picture without white is a production red.
