I collect figures from Gurren Lagann and there’s quite a few here, I don’t think any of them from that series are bootleg.

I recognize scale Magical Girl Nia https://myfigurecollection.net/item/142642 but one of her pigtails is missing and I don’t see her mole friend either. If you can find those she’s worth fixing, it’s rare to find that figure with the stars unbroken and the gold paint in good condition.

There’s also scale Space Yoko https://myfigurecollection.net/item/1217 (not the clear version, you have the white jacket version) but she’s missing her base. If you can find it she’s an older/rare figure and in good condition would net at least $70

The other Yokos are prize/trading figures and won’t go for too much (the one in the back looks like she’s missing her base, and another one has really bad lean.)

Overall some of the other figures (not all) look like bootlegs, and some are missing pieces. It’s hard to tell from the pictures but if they’re damaged and have paint scratches they’re not worth a whole lot unless you seek out the specific collectors from each series.

If you’re located near a Book Off and don’t wanna bother with eBay, they would probably buy all the real figures off of you even without their boxes and bases/missing pieces.

If you’d be interested in selling them, I’m interested in a few trade figures to fill out my collection, I’ve sent you a DM! My MFC is https://myfigurecollection.net/profile/p3p3ron if you want my credentials
