Okay, i stopped play before relics were a thing so I need clarification.

Are multiple relics per force possible? I have googled like crazy and I keep finding different answers.

Not generally. Normally you can add up to three objects to your force, but only one of them can be an immobile object, and all Relics are immobile objects.

There are, however, some mechanics (like the Book of the Skull or figures like Scorpio that bring their own Relic into the game) that make it possible.
