For armor, 6 is fine. 15 and 16 are being used personally. And 26 is actually just slightly modified colors of things already in game, and is in personal use. Though I don't have sprite sheets for any of them, so if you want to use them, you'll have to make those yourself.
For melee, 4 is in personal use, but the others you asked about are fine.
For ranged, 21 and 26 are in personal use, but all the others you asked about are fine.
And the hammer should be fine to use as well.
If you need, I can provide individual sprites for all the ones I've said are okay, and names for the few that have them if you want that as well. As for credit, a mention in the tooltips will do.
ok thank you, and yeah, i would like the names and individual files, thanks for offering ^^
