What genders are these chicks?

[Japsgalore]

Hi there,
I recently got 4 chicks from a breeder, 1 silkie, 1 Buff Orpington, 1 Polish and a Unknown breed. Anyway I was wondering if anyone would be able to tell the gender of these chicks?
Thanks to anyone that can!

Photos are mainly of there faces, since I’ve heard most people can tell it by their comb. Also just thought I should add I’m unsure of how old they are, I can’t remember as I have some memory issues.

1,2 - Buff Orpington
3,4 - Silkie
5,6 - Polish
7,8 - Unknown breed

I'm not 100% sure
#4 looks like a cockeral
#3 a possible pullet*
#2 a possible pullet*
#1 I'm on the fence the second photo indicates cockeral, however, camera lighting can play tricks on comb colour
(*idk but have heard wattle absence can indicate female)

Back again after a while! Chicks in photos 1, 2, and 3 ended up being pullets
Chick in photo one looked like they were a rooster but they were just a fast grower.
