Kakashi would likely be amused. He might give Naruto some tips on how to blend in as a girl, like using a more gentle voice. He would also be keeping an eye on Naruto to make sure he doesn't accidentally give away his true identity. Shikamaru would probably think it's too troublesome at first, but then he'd start to see the strategic advantages of Naruto's disguise. He might even come up with some clever plans to make use of Naruto's new identity in their missions.
Sakura might be really surprised at first. She could offer to help Naruto with his girl disguise, teaching him things like how to do his hair or choose the right clothes. She might also find it a bit funny but would be supportive in the end, seeing it as part of a mission. Sasuke, on the other hand, might be a bit more aloof. He would probably just raise an eyebrow at Naruto's new look but wouldn't make a big fuss about it as long as it was for a good reason.
His other friends like Shikamaru would try to analyze the situation. Shikamaru, being the intelligent one, would look for patterns in Naruto's 'insane' behavior. He might suspect it's a ruse, but he would also consider the possibility that Naruto is actually in trouble. So he would try to approach Naruto carefully and talk to him to find out the truth.
As for Shikamaru, he would probably find the whole situation too troublesome. He might avoid 'female Naruto' at first, but then when he realizes it's really Naruto, he would start to give advice on how to handle the situation in the most efficient way, like how to avoid unwanted attention from other guys.
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.
His friends would be shocked at first. Sasuke, for example, might see it as a sign of weakness on Naruto's part, that he let Minato do this to him. Sakura would be worried about Naruto's well - being and would try to find a way to reverse the process. Shikamaru would be thinking about the long - term consequences for the village and for Naruto's relationships. Overall, they would be very concerned and try to get Naruto back to his normal self.
Sakura might be really surprised at first. She could be a bit skeptical about whether it's really Naruto or some kind of trick. But then she would probably try to help him find a way to change back.
Sakura might be a bit surprised at first. She would probably tease Naruto a little about it, but then she'd also be curious to see what's in those fanfics. She might even start reading some herself to see how the fans portray her relationship with Naruto.
His friends like Kakashi would be cautious yet supportive. Kakashi would likely give Naruto advice on how to handle the relationship and the responsibilities that come with it. In Kirigakure, Mei's comrades might initially be distrustful of Naruto, but as they see his good intentions and how he treats Mei, they would gradually accept him. And Naruto's friends from other villages he has befriended over the years would see it as a positive step towards a more unified ninja world.
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.
Kakashi would be quite impressed by Naruto's creativity in using the clone jutsu in such an unorthodox way. He would also be cautious though, knowing that any new and untested jutsu can have unforeseen consequences. His friends from Team 7 would also start to think about how they could incorporate this new form of Naruto's clone into their battle strategies. For example, they could use the black book clone to gather intelligence or as a decoy in a more complex and unexpected way.
