I have:

Hardwire DL-8 delay/looper
Hardwire SC-2 valve distortion
Hardwire HT-2 tuner
Hardwire CR-7 chorus
Vox v847 reissue wahwah

How would I order them from amp > guitar?

Also, on another note, i just bought the vox but when i turn it on there is some buzzing and it sucks a little bit of tone, will I need to get the true bypass mod? If so, what do I need to buy?

A likely order would be tuner>wah>distortion>chorus>delay. A general rule is things like filters (wah, compressor) go early in the chain, then your distortion, and then time based effects like flanging, chorus and delay go towards the end.
Haven't you heard?

Does your amp have an effects loop?

Nope, just input.
