Old jar of marbles Need help with ID Part 1

[Mothra]

I bought a jar of old marbles… I’m not sure about them, as I know very little about marbles. I tried to pick out some of what I thought were the more unusual ones and took a lot of pictures. Any help with ID would be greatly appreciated. I also want to learn which ones I should keep vs giving to my nieces to play with. Thank you in advance for the help!

so far:

4. Newer Imperial

Thank you in advance!
