As usual, last names only are fine. Note that the seasons are the years over which they had their multi-homer games, not necessarily all the years the played for the Diamondbacks. Some obvious names on the list, but some might surprise you. Not included: Damion Easley and Shea Hillenbrand, who may be two of only nine Diamondbacks to have had a three-homer game, but neither ever again hit more than one for us. Indeed, Easley only hit nine in total for Arizona, so getting one-third of those in a single contest is kinda impressive!
