Need some help identifying figures, 2004-2014ish

I finally went through the last bit of mine and my wifes figure collection from our move several years ago, and there's a bunch of stuff we got in grab bags over the years that we're not entirely sure what it is. I have some ideas, but if anyone can help out, i'd greatly appreciate knowing what these figures are.

Edit: Everything is now solved except for Figure 7, this is still a mystery

Edit 2: Found figure 7, Conifer from Persiom https://myfigurecollection.net/item/102422

Figure 7

No idea on this one

All of these ones are solved now, thank you for your help!

I'm guessing this is a Gamera figure?

I think this is from Sakura Wars? It has a Sega Copyright on the underside of the base

I'm pretty sure this is from Naruto, but i've never watched/read the series

Reasonably certain this is a Gundam trading art, outside of that I have no idea

Figure 10 - Solved - https://myfigurecollection.net/item/8859

This one just never assembled, I'm wondering what it is before i toss it. The pegs were too large for the holes, so it was completely defective, probably why it was in a grab bag
