The red one looks like a Cream Legbar mix (I so wanted my EEs to have those little crests!), and the comb always throws me on those, so I would be of zero help there.
The light one is tough, too. The feathering does sort of have a pattern, which would indicate pullet. Males are more blotchy and often have rust-colored spots on their shoulders. But that's a big comb for 7 weeks. Does it ever turn really red?
I have a sexed-as-a-pullet EE cockerel the same age as your EEs. This was taken yesterday--he's on the left, obviously--and you can see how red his comb is, and not just when he's trying to look tough in front of an older bird. It started turning red at 4 weeks.
