Usually what I do (and did in progression) is just assign at least 1 hunter to kiting one of them, and tell the melee they should help with that too (taunting and keeping them away from boss).
1 of the infernals should always be on top of the boss, tanked by your active tank (not on banish).
The idea is to focus dps and burst the infernal near boss, then the tank taunts another one and that one gets focused.
