#1 looks like many Gold Sexlinks, but not sure about that one or the mottled looking one.
#2A and 2B are both SLWs.
If #4 has a flat (rose) comb, it's a Blue Laced Red Wyandotte. Similar breeds at that age are Welsummers and Speckled Sussex, both having single combs.
5A and 5B are Barred Rocks if they have single combs, if flat comb, Dominique.
