His friends' reactions would vary. Hinata would be really happy for Naruto. She would be gentle with the little girl and offer to make her clothes or cook for her. Kiba might be a bit skeptical at first, thinking Naruto might not be fully prepared for raising a child. But when he sees how much Naruto cares, he would be more accepting. Choji would probably be excited and share his snacks with the little girl right away, showing his warm - heartedness towards Naruto's new family member.
Sakura might tease Naruto about it a little. She'd probably think it's a bit strange that he's interested in something so different from their own world. But she'd also be curious to know what it's all about.
Well, Kakashi would likely be very cautious. He would be concerned about the implications of Naruto being with the fem Kyuubi. He would want to make sure that Naruto was not being manipulated in any way. He might keep a close eye on their relationship and offer advice to Naruto when he thought it was necessary. As for the other Konoha 11 members, some might be more accepting. They might see it as Naruto's personal choice and be happy for him if they saw that the relationship was a positive one. But there would also be those who would be hesitant, especially if they thought the fem Kyuubi could pose a threat to the village in the future.
Kakashi would be more of a supportive figure. He has seen Naruto and Sakura grow up, and he would likely be happy for them. He might offer some advice to Naruto on how to handle this new relationship, especially considering the challenges they might face as ninjas. For Sakura, he could give her words of encouragement to be true to her feelings.
Sasuke might initially be a bit aloof but secretly be happy for them. He's always had a complex relationship with Naruto and Sakura, and deep down, he would see that they are good for each other.
Sakura might be a bit surprised at first but would quickly support Naruto's choice if she sees that Fem Kami makes him happy. Sasuke would probably be indifferent on the surface but secretly happy for Naruto as long as it doesn't interfere with their own goals. Shikamaru would likely think it's a troublesome situation but would also go along with it as long as Naruto is sure about what he's doing.
Sakura might be a bit worried at first. She's always been concerned about Naruto's safety, and a new weapon like Zabuza's sword could seem dangerous. But she would also trust Naruto's judgment in the end.
Sasuke would be very suspicious at first. He's always been cautious about Naruto's new powers, and this one, which has the ability to take other people's powers, would make him wonder if Naruto was going to change. Sakura would be worried about the moral implications. She'd try to talk to Naruto about using it for good. Kakashi, on the other hand, would be more understanding. He'd see it as just another power Naruto has to learn to control and would offer his guidance on how to use it responsibly.
When Naruto's friends see him with the Spartan armor, it would cause a stir. They would all gather around, asking questions. Some would be excited about the new possibilities it presented, while others might be worried about where it came from and if it was dangerous. Naruto would have to explain what he knew about it, and they would all start brainstorming about how they could use it in their future battles or missions. They might also have to deal with any jealousy or envy that could arise if the armor seemed to give Naruto an unfair advantage.
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.
