I think the ones marked 4 are pekins! And the others could possibly be ancona but I'm not positive

I think the ones marked 4 are pekin as well! And the one marked 1 looks to be a mallard or a rouen.... And the others look like Ancona to me too! And I think 2 might be a Welsh Harlequin, but I can really see him/her
