Sexing silkies

[Fwoof]

Can anyone tell me what they think the sex is for any of these? Not my chickens can’t get more pictures trying to see sex before I buy. Thank you

Silkies are notorious for being very difficult to sex, but I'll try.
That frizzle one has suspicious hackle feathers that leave me wondering, But don't take my word for that. Could still very well be a hen.
The rest look female so far to me.
