They make special wire nuts for grounds. THey have a hole in the tip. So you take the ground from the feed wire, run it through the wire nut, and wrap it around the ground screw on each of the 3 switches. You can wrap it around the first switch in the middle of the wire (a "rabbit ear") then continue to the next switch. You don't have to pigtail to each device. then take your 3 ground wires coming from the light fixtures and tie them into the nut (but not through the hole in the tip).
Big box stores sell these nuts, they are green.
