Help identifying miniature pieces.

[mindfad]

I was recently going through ebay, and have found some loose miniatures that I can place. Was curious if anyone has any idea, going to try and attempt to track down the source.

I have asked the sellers and they have no idea. I feel like I have a good sense of what minis exist especially from board games and these ones are not triggering any ideas for me.
