AI-genrated art like this makes me happy. (As opposed to non-curated slop)
This stuff looks really good.
They aren't icons, exactly, though. I'm giving you 5/5 because these do look great. It's still kinda obvious that an AI made most of 'em, but...I think if you can figure out how to simplify and animate them (think spinning Mario coins or a treasure chest that opens), you'll have something very marketable.
But...these all look great. I got a serious "Metroid" / planetary sample vibe from most of them. Whatever you're doing, it's working. Just try to think about how to remove the backgrounds and such; lots of these might go great into another project if you can package them that way.
I think my favorite one is actually in the preview, with the red crystal.
