Obviously, Harry himself is a common character. Hermione is also often included as she is Harry's closest friend and very intelligent, so she can help Harry figure out how to navigate the past.

Dumbledore is also a character often paired with Snape in such fanfictions. Snape's loyalty to Dumbledore in the original story is complex. When he travels back, their relationship could be rewritten.

Sokka would also be a common character. His strategic mind could be very useful in a different time period.
