Her friends usually rush to her aid immediately. Percy, for instance, would be very protective and might even get angry at whatever or whoever caused her harm. Grover would use his nature - related skills to try and find herbs or something to heal her. The rest of the group would also form a protective circle around her, making sure no further harm comes to her while they figure out how to treat her wounds.
Her friends' reactions can vary. Percy would be full of rage and determination to get revenge on whatever hurt her. Meanwhile, some of the more strategic friends like Clarisse might start planning how to prevent future attacks. The younger demigods would look up to Annabeth and be really scared for her. They might cry or be in shock. But overall, they would all come together as a community. They'd take turns staying by her side, bringing her food and water, and making sure she has everything she needs while she recovers.
Annabeth would be very shaken up. After the initial shock, she would assess the situation calmly. If Percy is unconscious, she would try to find a way to wake him up. She might talk to him, recalling their memories together, hoping it would reach him on some level. And she would be very protective of him while he's injured, not allowing any further harm to come to him. She would also feel guilty, thinking that if she were stronger or more careful, Percy wouldn't have had to protect her and get hurt in the first place.
His friends would be extremely worried. They might immediately drop whatever they are doing to rush to his side. For instance, Thomas would be right there, trying to assess the situation and figure out how to help. He would be filled with a sense of urgency and determination to get Minho the care he needs.
Her friends would likely be very worried. They might rush to her side immediately.

Hermione would usually be very worried and immediately start looking for ways to heal him. She might use her knowledge of magic to find the right spells or potions to treat his injuries.

Fluttershy would be gentle and offer to take care of Twilight, using her animal - handling skills to find herbs or other remedies.
Her colleagues would be very concerned. Voight, as her boss, would probably be angry at the situation that led to her getting hurt and determined to bring those responsible to justice. Jay would be extremely worried and would likely stay by her side at the hospital as much as he could, constantly checking on her condition.
His friends would most likely rally around him. Kiba might use his dog Akamaru to scout the area and make sure there are no other immediate threats. Hinata would be really worried and would try to use her Byakugan to see if there are any hidden enemies or if Naruto has any internal injuries. Choji would offer some of his food to Naruto to give him strength, as his clan's food can have special effects on a ninja's body.

Her friends from the Athena cabin might be very methodical in their approach, helping her plan for the baby's education and future role in the camp. Meanwhile, some of the more impulsive friends might be a bit too over - eager, like suggesting crazy names or trying to throw an early baby shower without really thinking things through.
Inuyasha would likely be very angry and protective. He'd probably rush to her side immediately and vow to take revenge on whoever or whatever caused her harm. His reaction would be intense, as he has deep feelings for Kagome.
