In fanfiction with Naruto acting stupid and weak, how does it affect his relationships?

Well, in such fanfictions, Naruto's stupidity might make some characters more protective of him. For example, Sasuke could be more annoyed at first but gradually become more concerned as he realizes Naruto's good heart beneath the 'stupid' actions. And Sakura might scold him more often, but still care for him in a sisterly way. It can create some interesting dynamics in their friendships.

Well, his friends might start to feel like he's drifting away. Since he's hiding his strength, he can't fully participate in training or battles as they expect. For example, Sakura might think Naruto is being lazy or not trying hard enough, which could create some tension between them.

His malnourishment could make his friends worry more about him. For example, Sakura might start to be more motherly towards Naruto, constantly trying to get him to eat proper meals. His relationship with Sasuke could also change as Sasuke might initially look down on Naruto for being weak because of the malnourishment, but then as he sees Naruto's determination to overcome it, he gains a new respect for him.

With Sasuke, it could either drive a wedge or bring them closer. If Sasuke blames himself for Naruto getting injured while protecting him, he might distance himself out of guilt. On the other hand, it could also make Sasuke realize how much Naruto means to him and he could become more committed to their friendship.

His apathy can strain his relationships. His friends might feel neglected. For instance, Sakura could be confused and hurt as Naruto no longer shows the same eagerness to be part of the team.

His illiteracy might make his friends initially frustrated. For instance, Sasuke, who is more studious, could be impatient with Naruto's inability to read important messages. But as they grow, they might become more understanding.

When Naruto becomes Hinata, his relationship with Naruto's friends would be complex. He'd be in a female body and have to navigate through the different expectations society has for Hinata. His relationship with Kiba and Shino, Hinata's former teammates, would become more personal as he now shares Hinata's memories and feelings. And his relationship with Naruto's old crush, Sakura, would be a bit awkward as he tries to act like Hinata.

It could make some relationships stronger. His friends might be in awe of his new powers and look up to him even more. But it could also create some distance, as his new status might make others feel inferior.

With Sasuke, Naruto's past - life memories could have a huge impact. If he remembers a past life where they were either enemies or allies in a different context, it would change the way they interact. For example, if they were bitter enemies in the past life, Naruto might be more cautious around Sasuke, but also more determined to change their current relationship for the better. And when it comes to his relationship with the village, the villagers might view him differently. They could be either more in awe of him if his past life was of a great hero, or more suspicious if his past was somehow associated with a dark past.

It can create misunderstandings. For instance, his friends might think he doesn't like them if he recoils from their touches. His romantic relationships could also be affected. If he's in love with someone in the fanfiction, his fear of touch would make it difficult for him to show physical affection, which is an important part of a romantic relationship.
