Closed: PC on some items

Hello Folks - I have read the PC guides a few times - however my understanding is still quite limited. Please advice if any of the items here is worth anything (I am a new player and gold is hard to come by). Thanks

Going down the columns. Probably all going to be merch, but I'll be specific for future benefit.

1: Single mod, merch.
2: Req 11, undesirable non-max inherent, merch.
3: Req 12, non-max inherent, merch.
4: Purple, worthless inherent. Merch.
5: Purple, non-max unwanted inherent. Merch.
6: Unwanted inherent (and nowhere near max), merch.
7: Unwanted inherent, merch.
8: Req 13, mixed mods (fire req, water HCT). Merch. Salvage +30 health if you like.
9: Purple, unwanted/worthless inherent. Merch.
10: See 8.
11: Req 13. Merch.
12: Missing an inherent mod. Merch. Salvage mods if you like.

Salvage any mods you want and merch everything.
