I would send 3 and 4, and possibly 2 to a vendor or salvage. Cross-class weapons are hard to sell. In order to make full use of #4, you need to be a necro, monk, and ele! I guess if someone wants just a max staff you could sell any one of them for maybe 500-1.5k, but most people like weapons that are fully useable by their classes.
