Trying to correctly identify what I have

[Oddjane]

Hi, I have acquired a decent size collection of beautiful marbles and am struggling to identify some of them. I have quite a few. But I’ll start with the ones I’m struggling the most with. The first 4photos are the same marbles with and without backlight. They are throwing me off the most.  Thank you for your help!
