Naruto is the key character as the title implies his movement to Suna. Gaara will most likely be a main character as well. His leadership in Suna and his connection to Naruto make him a natural choice. Additionally, some of the Suna elders or other important shinobi might be involved as secondary main characters, as they could be the ones who interact with Naruto and influence the events in Suna.
There could be new characters created specifically for this fanfiction. Maybe a young Suna shinobi who becomes Naruto's guide in Suna, showing him around the village and introducing him to the local way of life.
One possible interesting scenario could be Naruto using his unique jutsu in Suna. For example, he might use his Shadow Clone Jutsu in a creative way to help with some sort of Suna - related problem, like rescuing people from a sandstorm. Another could be Naruto interacting with Suna characters in a new light, perhaps befriending some of the shinobi there who were previously wary of him.
Iruka sensei is almost certain to be in it. He has always been important in Naruto's life. Also, Sakura might be there. She could be one of the first to welcome Naruto or perhaps she might initially be a bit cold because of her past feelings for Sasuke. Other characters like Kakashi sensei could also make an appearance, guiding Naruto in his new life in Konoha.
There could be some old and wise shinobi in Suna that Naruto encounters. These shinobi could have stories about the history of Suna and its relations with other villages. Meeting them would give Naruto a broader perspective on the ninja world. Also, he might meet some civilians in Suna who are affected by the village's politics and shinobi activities. Interacting with them would make Naruto more aware of the real - life impact of being a shinobi in Suna.
Well, he might face a lot of challenges adjusting to the new environment in Suna. For example, getting used to the different climate which is much hotter than Konoha. He would also need to adapt to Suna's unique culture and traditions.
