My guesses:

1) 10kish I think
2) 5kish
3) Vastly depends on the skin variant. There are several different skins for Water Staff - check wiki and edit your post to clarify.
4) I'd salvage the inscription, then the core and sell those.
5) merch/salvage - Non-inscribable staffs w/out a second inherent casting mod are almost never worth the time to sell unless they're an extremely rare skin. Amber staffs are not very rare.
6) Same situation as the water staff - check wiki and edit to include which skin variant it is.

Cheers!
