First is an OEGB. Second has less than 50% the amount of foot/leg feathering a Cochin should have. Third has a beard, so d'Uccle. Fourth is a dark Brahma.
Can you get better pics of faces/combs on number 2 and 3?
Fawn silver duckwing old english, red cochin, d'Uccle- can't tell if it has any blue on it- if so then porcelain, if not then gold neck. The last is a dark brahma.
