My GFCI by the fuse box is not working. All other outlets are working when hooked to correct power (battery or home). The test button works. The reset button does not appear to stay in. I pulled the GFCI out and there were five wires coming from it. Can someone explain them to me? I need to replace the GFCI but most say three wire.

Your photo shows white (neutral) and black (hot) 115V going into the fixture and the red and gray should be the hot and neutral to a downstream protected fixture (the load). Not certain of the hot/neutral color of the downstream. And green is a ground. All GFCI outlets have the ability to be wired with all 5 wires you have (connecting to a load).
