Sakura would likely be very concerned. She's a medical ninja, so she'd first check Naruto's physical condition to make sure there's no underlying medical issue causing the panic attack. Then, she'd try to calm him down by speaking softly and reassuringly, reminding him of all the times he's overcome difficulties.
Choji would offer Naruto some of his favorite snacks. Food has always been a way for Choji to comfort himself and others. He'd hope that by sharing something delicious, he could distract Naruto from his panic and make him feel better. And his warm and friendly presence would also be a source of comfort for Naruto.
Yamato might first be a bit shocked. But then he'd probably try to calm Naruto down. He could use his wood - style jutsu to create a peaceful environment, like making a small forest around them to soothe Naruto.
Yamato might first try to use his calm and steady presence to soothe Naruto. He could place a hand on Naruto's shoulder and speak in a gentle voice, telling him to take deep breaths.
His friends like Shikamaru would likely find the whole situation tiresome at first. He'd be thinking 'What a drag, now we have to deal with Naruto and his pacifier.' But then he might start to see the humor in it and use it as a way to tease Naruto in a friendly way. Choji would probably be more sympathetic and offer Naruto some snacks to go with his pacifier, seeing it as something that makes Naruto a bit more vulnerable and in need of comfort.
Sakura would probably be the first to jump into action. As a medical ninja, she'd immediately start examining Naruto and try to figure out the cause of the fever. She might be worried but also very focused on treating him.
Friends could help Percy by distracting him. For example, they could tell a funny story or joke to take his mind off the panic. They might also encourage him to engage in relaxation techniques, like deep breathing exercises together. If they know what triggers his panic attacks, they could try to shield him from those situations, like if it's a certain person, they could keep that person away from Percy.
His friends can first be there for him. Just sitting with him quietly when he's having a panic attack can be really comforting. They can hold his hand or give him a gentle pat on the back to let him know he's not alone.
Sakura might be initially suspicious. She is a smart girl and would wonder about the butler's intentions. She might keep a close eye on him to make sure he doesn't harm Naruto in any way.
His friends from Team 7, like Kakashi, would feel responsible for Naruto's situation. Kakashi would likely use his resources to find a proper shelter for Naruto.

They would pool their resources, like money and food, and also try to cheer him up by sharing stories and jokes.
Sasuke, who has his own complex relationship with Naruto, would probably be in denial at first. He's seen Naruto as this strong - willed person, and the idea of him having schizophrenia would be hard to accept. But as time goes on, he would become more protective. He might train Naruto in ways to control his mind during the episodes, using his own experiences of mental discipline. As for Kakashi, he would be empathetic. He has his own traumas, and he would do his best to support Naruto, maybe sharing his own stories of dealing with difficult mental states.
In this fanfiction, Naruto's panic attack might be caused by the pressure he feels. He has so many responsibilities, like protecting the village and his friends. Yamato might be a trigger because Naruto doesn't want to show weakness in front of him, but the stress gets to be too much.
