To Frizzle or Not to Frizzle

I have some lovely straight run silkies I got a while ago. Probably around 7 weeks now give or take. I have an obvious frizzle but I am hoping I have some regular silkies as well. I WANT to keep any roosters I have but don't want them frizzle do to frazzle risk. So. Any insight as to who is a frizzle and who isn't?

The last one is my OBVIOUS frizzle. So you better be a pullet, Olive .... but I'm really confused as to my other two. The blue I can't tell if he's normal silkie or frizzle silkie. And the second chocolate mottled is ....well .... not like Olive but not entirely smooth feathered. so ....IDK. Wickett is my first satin silkie so I'm not entirely sure if that's just how their feathers grow out.

The First 2 pictured are Blue. The second two are Wickett. And third is obvious Olive for comparison.
