When it comes to describing people who are loyal and devoted, "faithfuls" is a great term to use. However, if you're looking for some synonyms to switch things up, you could consider using words like "devotees," "followers," "supporters," "adherents," or "disciples." These words all convey a sense of allegiance and dedication, just like "faithfuls" does. Other options could include "believers," "faithkeepers," "practitioners," "worshippers," or "zealots." No matter which word you choose, be sure it accurately reflects the level of loyalty and devotion you're trying to describe.
