His friends' reactions would be quite diverse. For Sakura, she'd be really excited and would probably start nagging Naruto to share all the details of how he achieved it. She might also see it as motivation for herself to work harder. Sasuke would be more reserved in his reaction. He might give Naruto a nod, which for Sasuke is a big sign of respect. Shikamaru would just shrug it off like it was expected but deep down be glad that Naruto is growing as a ninja. Choji would be all smiles and offer Naruto some of his favorite snacks to celebrate. Kiba might be a bit grumpy at first, saying Naruto got lucky, but then also congratulate him in his own way.
Sakura would probably be both proud and a bit envious. She has always been competitive with Naruto, so while she'd be happy for him, she might also feel like she needs to step up her game. Sasuke, on the other hand, might show a small smirk of approval. He respects Naruto's growth, even if he doesn't always show it. Shikamaru would likely be like 'Well, it was about time, dobe.' in his usual laid - back but supportive way.
Sakura would be very vocal about her support. She'd be cheering Naruto on and might even start thinking about how she can help him in his new role as a Chunin. Sasuke's reaction would be a bit more complex. He'd see Naruto's promotion as a sign of his own need to progress further. He might challenge Naruto to a friendly spar later to see how much he has really improved. Shikamaru would use this as an opportunity to slack off a bit more, saying that Naruto can handle more of the work now. But in reality, he'd be happy for Naruto. His other friends like Ino would be congratulating Naruto and might start spreading the news around the village, making Naruto a bit embarrassed but also feeling very loved by his friends.
