Along with my previous post about dice ID, I would love some help IDing these plastic miniatures.  I'm pretty sure they belong to games, and I would love to know what they are so I can describe them correctly to help people complete their sets if they happen to be missing these.  Of course, using them purely as miniatures is fine, too, I just love completing things, either my own or someone else's.  Thanks for the time, as always!

Some of the human ones gave me a Shogun / Samurai Swords / Ikusa vibe, so you might look into that, but I have to admit that I don't think that's exactly right.
