When it comes to his relationship with Pain himself, it would be complex. On one hand, Pain would be like a father figure. But on the other hand, Naruto might struggle with some of Pain's teachings as he has his own innate sense of right and wrong. He could be in a constant internal battle between following Pain's lead and his own moral instincts.
Naruto's relationship with other ninja villages would also be different. He might view them with more suspicion as Pain taught him to be wary of others. He would not have the friendly rivalries he had in the original story. Instead, he could be more likely to engage in hostile actions if he felt threatened by other villages.
His relationship with the Hidden Leaf would be strained. He might see the village as a source of weakness rather than a place to protect. And his friends in the village, like Sasuke and Sakura, would be more like strangers to him. He would not have the same bonds that were formed through growing up in the Leaf.
His relationships would be very different. He wouldn't have the same connection with Jiraiya, for example. Instead, he might be mentored by an Iwagakure ninja. His relationship with the other villages would be more strained, as Iwagakure has a different history of relations with them. And his relationships with his peers in Iwagakure would be based on the Iwagakure way of life.
If Naruto was raised by Orochimaru in fanfiction, his relationships would be turned upside down. His friendships from the Leaf Village would be in jeopardy. Since Orochimaru is not one to value the kind of loyalty and friendship that Naruto's friends in the Leaf do, Naruto would have a hard time understanding and maintaining those relationships. He might even be hostile towards them, seeing them as obstacles in his pursuit of power. His relationship with the Hokage would also be a mess. Instead of looking up to the Hokage as a role model, he would probably view the position as something to be conquered or undermined, following Orochimaru's ideology of power - seeking.
If Naruto was raised by Obito, his relationships would take a radical turn. With the villagers, he would be seen as an outsider or even a threat, just like Obito was in a way. His relationship with Sakura would be different too. Without the common experiences in the village, he might not have the same friendly - rival kind of relationship with her. And his relationship with the Akatsuki members could be very different. He might be more inclined to understand their motives or even join them at some point, given Obito's connection to the group. It would create a whole new web of relationships that are far removed from what we saw in the original Naruto story.
Naruto's relationships would see a significant shift. In the context of his family - like relationships, he'd have a whole clan to call his own. The Inuzuka would be his family, and he'd have the support and guidance of the clan elders. His relationship with Hinata might not develop in the same way as in the original story. Given his Inuzuka upbringing, he might be more attracted to someone who is more in line with Inuzuka values, like being strong - willed and having a connection to animals. His relationships with his enemies would also be different. His Inuzuka - trained combat skills and the reputation of his clan would make his enemies approach him with a different level of caution and respect.
Naruto's relationships would experience a significant shift. With Sarutobi as his guardian, he would have a closer relationship with the Anbu. He would be more involved in the inner workings of the village at an earlier stage. His relationship with Kakashi would also be different. Instead of Kakashi being his main mentor, Sarutobi would play that role. This would mean that Naruto would approach his training and missions with a different mindset, which in turn would affect how he relates to his comrades and opponents.
Naruto's relationships would be transformed if raised by Gogeta in this fanfiction. His connection to his village would be different. He might not feel as strong of an emotional attachment to Konoha as he did in the original story. In terms of his friends, he would be more of a loner in a sense, but also a figure of mystery and power. His relationship with Kakashi would also be altered. Instead of Kakashi being his main teacher, Gogeta would fill that role. This could lead to Naruto having less of a traditional ninja - like view of relationships and more of a Saiyan - influenced view, which could be more about strength - based alliances and mutual respect for power.
His relationships would be drastically different. For example, his relationship with Sasuke would be strange. Sasuke might be both intrigued and scared of Naruto's new powers. And Naruto might not have the same bond with his original friends from the Leaf Village as he's now more in the vampire world.
He'd be more cynical. Orochimaru's ways would make Naruto question the goodness in people.
With Sakura, Naruto might not have the same kind of unrequited love. If he is raised by Uchiha, his values and priorities could be more in line with the Uchiha way of life. He may see Sakura more as a friend or comrade rather than having romantic feelings for her. Also, Sakura might be more intimidated by Naruto if he has Uchiha - like traits.
His relationship with Sasuke might be affected. Naruto might approach Sasuke differently, with new strategies learned from Zetsu. He could be more secretive about his intentions towards Sasuke, which might either make Sasuke more curious or more distrustful. With his friends in Konoha, they might be a bit wary of Naruto at first because of his new training source. But once they see that Naruto is still on their side, they would support him.
