In this 'naruto conquers konoha fanfiction', Naruto's closest friends are likely to support him. For example, Hinata, who has deep feelings for Naruto, would be by his side. She believes in him wholeheartedly. Kiba, with his straightforward nature, might also be convinced by Naruto's ideas. Moreover, the members of Team 7 like Sakura, after some initial hesitation, could come to support Naruto once she realizes that his actions are for the greater good of Konoha and all its shinobi.
I think Rock Lee would be likely to support Naruto. Lee has always admired Naruto's spirit and determination. He would probably believe in Naruto's vision for a better Konoha. Another one could be Choji. He and Naruto are friends, and if Naruto explains his noble intentions, Choji would likely stand by him. And of course, Kakashi, who has seen Naruto grow, might also support him if he realizes that Konoha really needs a radical change.
Sasuke could be one of the characters to support Naruto. They have a deep bond, and Sasuke might understand Naruto's reasons for wanting to change Konoha. Also, Shikamaru, being a smart strategist, might see the potential in Naruto's plan and choose to support him.
Sasuke could be one of the characters to support Naruto. Given their complex relationship and Sasuke's own issues with Konoha in the past, he might see Naruto's cause as just. Another one could be Jiraiya. If he were alive and found out about the real reasons behind Naruto's revenge, he might side with Naruto as he always cared for him deeply. Also, some of the outcast ninja within Konoha, like those who have been discriminated against because of their bloodline or lack of skills, might support Naruto as they also have grudges against the village system.
Definitely Sasuke. Their bond is such that Sasuke would not stand by and let Naruto destroy Konoha. He has his own reasons to protect the village now. Shikamaru is also a likely candidate. He's intelligent and would quickly figure out that Naruto's actions are wrong. He would use his strategic mind to try and stop Naruto. And Hinata, who loves Naruto deeply, would oppose him in the hopes of bringing him back to his senses.
Sakura might support Naruto. Despite the exile, she could believe in his innocence and try to find ways to help him. Also, Kakashi, who has always had a connection with Naruto, would be likely to support him. He might secretly provide Naruto with some resources or training advice.
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.
Iruka could be one. He has always believed in Naruto from the start. Also, Jiraiya might be another. He was Naruto's teacher and had a deep understanding of Naruto's potential. And Kakashi could also support him. He has seen Naruto grow and might recognize his sage powers even when others don't.
In a 'naruto conquers konoha fanfiction', perhaps Naruto could be pushed to the edge by the corrupt system in Konoha. He might decide to take over to bring real change. He could use his powerful jutsu and the loyalty of his friends to overthrow the old regime and install a more just rule.
Sasuke would likely be involved. He has his own issues with Konoha and might side with Naruto, either out of friendship or his own vendetta against the village. Also, the elders of Konoha like Danzo could be important characters as they might be the ones behind Naruto's banishment.

The village elders are very likely to be involved. They often have a say in the big decisions in Konoha. They might be the ones who decide that Naruto must return for the safety or the benefit of the village. Tsunade could also be a part of it. If she's still in charge, she might be in a difficult position of having to order Naruto back or deal with the consequences of his forced return.
