Help with some tsuba mei

[Katsujinken]

A friend recently visited the Cleveland Museum of Art where they apparently have over 200 tsuba in their collection but essentially zero information about any of them. It's a bit of a shame, really. Blades are more my area so I'm little help with some of these kanji/kao...

 

I offered to try and enlist some help to translate a few signatures. Thanks in advance!
