Elemental and regular stat buffs do indeed stack. Makes mono teams desirable, although the only one I'd reccomend would be mono-earth or mono-light.

Conversion buff is essentially Boost X stat based on Y stat. They don't stack with each other (a Boost X based on Y won't increase in accordance with the increase from a boost Z based on X - it'll still increase, but it won't take into account the extra increase from the first boost iirc)

And yes, both elemental and general stat buffs should apply to the conversion buff.
