It's still very early, but 1, 3 9, 12, and 13 are cockerels.
For the silkes you will have to wait until they are several months old to tell.

x2, so far 1, 3, 9, 12, 13 look like boys with the redness of combs.

An update on my two marans (#12 and 13) at 7 weeks: I thought both of them were cockerels. One of them is definitely a cockerel, but I am a bit unsure about the other.
The last picture is of the cockerel. His comb is larger, red and his back feathers are copper coloured. The other one’s back feathers are black. What do you think?

Last one is a cockerel for sure (as you note, the copper feathers on back) but I'm not sure about the first bird.
