I'm pretty all 3 body types can survive a direct hit from the DL, although the lights may do it just barely. Grenades are not damage focused in the game, they are more for knocking people over.
But there are so many variables to what youre asking, its hard to say. Are you asking headshots? bodyshots? SMG? AR? standard clip? extended clip? unbuffed? buffed? range?
It might take take 1 SMG clip point blank, 2 at medium range if they dodge, a few to the head, maybe cut the numbers in half if you are talking buffed ARs , but then they have a slower fire rate. And then its just guesswork on top of it.
Basically, what I'm saying is that the numbers wont be as clean cut as they are in other games.
