the symbols could represent the people involved with the apocalypse since Gideon starts the event by releasing Bill, Stan and Ford being involved with the gateway such Ford building the portal while Stan causing the rift and last but not least Mabel causing Bill to access the rift.

If the symbols are meant to be warriors against Bill why wouldn't he kill Dipper, Mabel and Soos and render Stan brain dead if they are essential to the story? and could possibly kill him or trap him?

I am overthinking it. it could just be a fun connection to all the characters or to mislead the audience.
