Yes, they are all additive. Quick's Star Generation up is additive pretty much because every form of star generation is additive.

Arts' NP gen up is additive and synergizes multiplicatively with overkill.

Buster's damage up is additive and synergizes multiplicatively with all attack bonuses except for buster chain and flat damage up from things like Divinity.
