Do my best here ...
First off, salvage popular mods and sell separate. PC guesses are for the skins/reqs/inherent mods when applicable without pricey mods attached.
1. r10 inherent 15^50 gold Forked Sword - not too sure of price, but probably worth selling for at least 5-10k, maybe more?
2. r9 inherent 20wH gold Recurve Bow - alas, it's probably merch food. The skin is not very popular or rare (

) and the inherent damage mod is not desirable. Unless you manage to find a collector, I can't see anyone buying that for even 1k. Sorry.
3. r9 inherent -disease Inscribed Staff - like the bow above, I think it's merch food. The inherent mod kills it.
4. r9 nonmax gold insc. Bone Staff - merch it. Neither the base damage or HSR on that staff are max.
5. r11 nonmax insc. gold Flatbow - merch it. Like the bone staff above, the base bow is not max damage.
Sorry I didn't have better news for you.
