Naruto might encounter other Jinchuriki. Since he is a Jinchuriki himself, meeting others could lead to interesting exchanges. They could share their experiences of living with a tailed beast. It could also lead to a new alliance or a new understanding between different villages that have Jinchuriki among their ranks. Another possibility is that he meets some wandering ninjas who have unique skills and abilities that Naruto has never seen before.
He could meet some old enemies who have changed their ways. For instance, some of Orochimaru's former minions might have decided to start anew and cross paths with Naruto. Or perhaps he meets a hermit ninja who has been living in isolation for years and imparts some valuable wisdom to him.
There's a chance that Naruto meets some of the previous Hokage in a spiritual or mystical way during his journey back. They could give him advice on how to lead the village in the future. He may also meet some young ninjas from other villages who are on their own training trips. This could lead to friendly competitions and exchanges of ninja knowledge between them.
