The friends from Gaara's village, like Temari and Kankuro, would be very protective. Temari would likely give Naruto the 'big sister' talk, warning him to take good care of Gaara. As for Naruto's friends, they would support him wholeheartedly. Choji might bring over some of his favorite snacks for Gaara, thinking it would be good for the baby. And Hinata would be quietly supportive, maybe knitting some baby clothes in her spare time.
Sakura's reaction would be complex. She has deep - seated feelings for Sasuke, so it would be a hard pill to swallow. However, as a medical ninja, she would also feel a sense of responsibility towards Sasuke's pregnancy. She might offer to be Sasuke's doctor throughout the pregnancy. Naruto's friends like Rock Lee would be over the moon for him. Lee would see it as Naruto achieving another great milestone in his life. He would constantly cheer them on and might even start training extra hard in case he needs to protect the new family. As for the other Konoha ninjas, they would initially be skeptical but gradually accept the situation as they see Naruto and Sasuke's determination to build a family together.
The Uzumaki family, if any are still around, would be overjoyed at the news of Fem Naruto's pregnancy. They would probably start preparing traditional Uzumaki baby items and sharing family stories with Naruto. In Gaara's case, the people of the Sand Village who once feared him might now see a new side of him and start to show more support and acceptance, seeing him as a future father and a more approachable leader.
Naruto's friends like Sakura and Kakashi might be initially shocked. Sakura, as a medical ninja, would offer her medical expertise to help Cana during the pregnancy. Kakashi would probably be more reserved but offer his wisdom and protection. On Cana's side, her friends from her own world might be skeptical of Naruto at first, but as they see how much he cares for Cana, they start to accept him.
Naruto's friends from Konoha would likely be very supportive. Kakashi might offer some wise words about the responsibilities of parenthood. Sakura would probably be there to help with any medical concerns Mirajane might have during the pregnancy. As for Mirajane's friends from Fairy Tail, they would be excited. Erza would be making sure Mirajane is well - protected and would probably train Naruto a bit to make sure he can defend his family. Gray might make some jokes to lighten the mood but also be ready to help out.
Sakura would likely be shocked at first. She might feel a bit of jealousy or disappointment as she had some feelings for Naruto in the original story. But being a medical ninja, she would probably also offer her help to Blackfire during the pregnancy. Kakashi would be more composed. He would probably give Naruto some advice on responsibility and how to handle the situation with all the political and social implications. Sasuke might be indifferent on the surface but secretly be a bit worried about how this would affect Naruto's standing in the ninja world.
Harry and Ron would likely be very shocked and concerned. They know Fenrir is a dangerous werewolf, and they might not understand how Hermione got into this situation. They would probably try to persuade Hermione to leave Fenrir at first.
Their friends might be really shocked at first. Some of them could be overjoyed, like those who are always rooting for Matt and Rebekah as a couple. However, there might be a few who are skeptical. For example, those who know about Rebekah's past might worry that she's not ready for motherhood. But overall, most of their friends would probably come around and offer support, whether it's helping with baby preparations or just being there to listen to their concerns.
Leonard would probably be really shocked at first. He's known Sheldon for so long and might not have expected him to become a father. Howard and Raj would likely be full of jokes and teasing, but also offer their support in their own goofy ways.
Damon would likely make sarcastic remarks at first but deep down be happy for them. He and Bonnie have a long history, and he'd come around to being supportive. Elena would be very emotional. She'd be there for Bonnie, offering advice based on her own experiences, even if they were different in nature. The other witches in Bonnie's coven might be a bit worried at first, fearing that the pregnancy could disrupt Bonnie's connection to magic or put her in danger from other supernatural forces.
Dustin would probably be really excited and offer all kinds of strange but well - meaning advice. Lucas might be a bit more cautious at first, but then warm up to the idea. Will would be very supportive and draw pictures for the baby.
