Their closest friends would probably be very supportive. They would congratulate them and start thinking about baby showers and gifts. However, there could be some more distant friends who are indifferent. They might just give a polite congratulations and not really be involved. And then there are those friends who might be worried. Maybe they think Jack and Sally are not ready to be parents and fear for the well - being of the baby.
Some of their friends might be overjoyed. They could offer to help with things like babysitting or bringing over home - cooked meals. Others may be a bit surprised, especially if Jack and Sally hadn't been trying for a baby for long. There could also be friends who are jealous, seeing Jack and Sally start a new chapter in their lives while they may be in a different situation.
Tails would probably be really excited. He'd be the helpful uncle, always ready to use his mechanical skills to make cool toys for the baby. Knuckles might be a bit more gruff at first, but deep down he'd be protective of the little one. Amy would be over the moon and would constantly offer to babysit so she could play with the baby.
Their friends would probably be really surprised at first. Orihime might be super excited and start making all kinds of baby clothes and accessories for them. Chad would be happy for them in his quiet way, and Ishida might be a bit more reserved in his reaction but still offer his support.
Rick would probably be very protective. He would see the baby as a symbol of hope in their post - apocalyptic world. He might offer extra protection around their living area and ensure they have enough supplies for the baby.
Their friends would be really excited. Mater would probably be the most enthusiastic, constantly asking if he could take the baby for rides in his tow truck (in a very safe way, of course). Doc Hudson, if he were still around, would offer some wise words on raising a child. The other cars in Radiator Springs would bring gifts and offer to help with babysitting or any other needs.
Then there are those friends who might be jealous. Maybe they've been trying to have a baby themselves and haven't been successful. So instead of being happy for Emma and Neal, they act a bit cold or distant at first. But as time goes on and they see how much love and care Emma and Neal are putting into raising the baby, they come around and become more supportive.
Ban would probably be excited and start thinking about all the fun things he could teach the baby, like how to steal food without getting caught in a humorous way. King might be a bit more reserved at first but then offer to make the most beautiful crib with his powers. Diane would be super excited and offer to babysit all the time, cooing over how cute the baby will be.
Nami would probably be shocked at first. She might worry about how this would affect Luffy's journey to become Pirate King. But then she would likely start thinking about practical things like how to take care of the baby on the ship. Sanji would be over the moon, seeing it as an opportunity to cook for a new little life. He might also be a bit jealous that it's Luffy and not him having a baby with Hancock.
Their friends might be initially shocked. Some of their more cautious friends could be worried about the implications of a child born to such powerful individuals. However, their closest friends would likely be very supportive and offer help in any way they can, like providing a safe place to stay or resources for the upcoming baby.
Some friends might be overjoyed. For instance, Stiles could be really excited and start making all kinds of plans for the baby shower. He might also be a bit overprotective, constantly checking in on Lydia and making sure she's taking care of herself.
Well, Serena would probably be over the moon. She's always been close to both Dan and Blair and would see this as a wonderful union. She'd be there for Blair during the pregnancy, helping her with shopping for baby clothes and giving her advice. Nate, on the other hand, would be more practical. He'd offer to help Dan with any financial or housing arrangements they need to make for the baby. And then there are the more catty friends, like Penelope and Hazel, who might be jealous and make snide remarks about how Dan and Blair got pregnant so quickly, but deep down they're just envious of their relationship.
