Mine lives in the living room, indoor Guinea.

The fireworks have never bothered him at all, a loud bang went off lastnight whilst he was sprawled out asleep, he lifted his head, and then settled back down lol he seemed more annoyed that it had disturbed his sleep than anything

He has a towel in his cage, which he sleeps under. He usually hides under that if something scares him.

Hope your Guineas are ok
