The one on top with the little crest is a Legbar based Easter egger.
The red one is a cinnamon queen
The blue one in the next photo is probably a blue Andalusian. Could be a blue Australorp as well, or Sappire Gem. When the earlobes mature, they will be white for Andalusians and red for Australorps and Sapphire Gems.
The black one could be many things. Australorp, black Andalusian, black Minorca, Jersey Giant, and others. The color of the mature earlobes will help determine what it is. Australorps and Jersey Giants have red earlobes, Andalusians and Minorcas have white earlobes.
The barred one is a barred Plymouth rock.
The white one with black spots is probably an Austrawhite. Splash Andalusian is another possibility.
The final blue one is probably a Sappire Gem.
