Most of their friends would be very supportive. However, there might be a few who are jealous. Some might be envious of the love they share. But overall, their friends would throw a huge celebration. Bulma would use all her resources to make the wedding a grand affair. And the Z - Fighters would put aside their training for a while to celebrate with them. There would be a lot of laughter, stories shared, and of course, some friendly sparring during the pre - wedding celebrations.
Gohan would likely be extremely shocked and angry. He is Pan's father and would have a hard time accepting this situation. Vegeta might be disappointed in Trunks, as it goes against Saiyan propriety. Bulma would probably be worried about the implications for the family and how to handle the situation. Goten might be confused and not know how to react, as it involves his nephew and niece in a very unexpected way.
Chad would be excited and happy for them. He's always been a loyal friend to Ichigo, and he would see Yoruichi as a great match for him. He might even offer to help with the wedding preparations.
Their friends' reactions would be quite diverse. For instance, Ino, who was once Sakura's rival, would have a mixed reaction. On one hand, she would be happy for Sakura as they have grown to be friends over the years. On the other hand, she might feel a bit envious. Choji would be excited and would look forward to all the feasts at the wedding. As for Lee, he would be over - the - moon for Naruto and Sakura. He would probably give them some long - winded and passionate speeches about love and friendship.
Their friends would probably be overjoyed at first. Spencer might be the practical one, making sure all the legal and logistical aspects of the marriage are in order. Aria could be super excited and start planning all kinds of post - wedding get - togethers and celebrations.
A common theme is the adjustment to married life. They have to learn to live with each other's habits. Another theme is family. They might think about having children or dealing with their extended families.
Hermione's friends from Gryffindor would be a mix of disbelief and concern. Neville, for example, would be worried that Draco might be using Hermione in some way. Luna would be more accepting, seeing it as a unique and interesting relationship that defies the norms of the wizarding world. As for Draco's friends from Slytherin, they would also be shocked. Some might see it as a betrayal of Slytherin values, while others might be intrigued by the power dynamics at play between a Muggle - born witch and a pure - blood wizard.
Their other classmates like Okuda would be very sweet. She might make them some special potions or concoctions as wedding gifts, something that symbolizes good luck and a long - lasting marriage. And she would be all shy and cute about presenting it to them.
Their friends would likely be overjoyed. Happy for the couple and excited to be part of the wedding. For example, Natsu might be a bit rowdy but full of genuine happiness for Rogue, while Erza would be more composed and offer practical help with the wedding preparations. Levy would probably be helping Lucy pick out the perfect dress and gushing about how romantic it all is.

Renji would be all excited and would probably want to show off some new moves during the wedding reception as a form of celebration. Orihime's friends from school would be squealing with excitement, constantly talking about the wedding and how beautiful Orihime will look. And Ichigo's dad would be a bit of a wild card, maybe causing some chaos in the name of celebration but also being really proud of his son.
Natsu would probably be really excited and might even challenge Laxus to a friendly fight right at the wedding reception, just for fun. Happy would be flying around, dropping flower petals everywhere and congratulating them. Erza would be very happy but also very strict about the wedding protocol, making sure everything is perfect. Gray would be a bit more laid - back, but still offer his congratulations with a cool smile.
