On Galuna Island Gray was just seconds away from "killing" himself via Iced Shell, until Natsu punched him.

With him being the sole survivor from his village, I think we can call that a brush with death and when he went after Deliora, he'd have died if it wasn't for Ur coming in and sacrificing herself.

So with the reversed death in the GMG that alread makes 4, without even looking at the "minor" stuff like being run through with a sword, getting close to being blown up by the etherion infused Tower of Heaven or being turned into a helpless Lacrima that needed saving by Gajeel.
