Beck's summaries: A to Z. Aurora: She carried on her attack on the invaders as 'Her' until she was probably apprehended by Jean-Paul in which case she probably reverted back to Jeanne-Marie and needed a hug/nap. Hah.
Britannic: Brian finally managed to get Lorna inside after she'd gotten the fight out of her system and went back to his lab duty. There were probably lots of things for the doctors to do, considering the number of people who were hit/injured/captured (Stryker's men, that is).
Dazzler: Was out of town.
Dukes: Took out as many men upstairs as he could before he joined the group in the lobby, then helped with the clean up outside in the yard.
Gambit: Was hit with darts but managed to stay on his feet throughout the fight after yanking them out. He probably went and passed out for a while (not in the infirmary) and then woke up ASAP to help out.
Grasp: Joined Levity in watching Brogan after finding through Beast that the darts weren't poisonous. He rejoined with Eva later to make sure she got some rest.
Storm: She accompanied the children (along with Crane) through the tunnels under the school and woods and got them to the safe house in town until there was an 'all clear'. Upon returning, she made sure they all got to bed and began handling any parental situations (phone calls, arrivals, etc), as well as helping with the clean up.
Tempo: She, Kitty and Jubilee made it to the hall passageway outside of the library and helped watch the younger students during the walk through the tunnels/into town. Upon returning, she found Jono to see if he was okay, then did double time (literally) on the lawn to help sweep up.
Torrent: Along with Chamber and Omen, he covered the backyard from further attack and the three of them most likely ventured into the woods (as well as some others) to seek out runaways for interrogation. Then, he went to fucking bed. Yeah.
Trance: He worked as the (deaf) lookout for Pyro and Sentient so that they could get to the tunnels, but they most likely got stopped a few times along the way and had to scuffle/run in the wrong direction. I'm going to guess they made it through (at least Trance and Sentient). John might've stayed to fight once they were at the passage way.
Zap: After Edan's arrival to Brogan's room, she joined Mars in the security room and helped him organize the counter attack and along with Matrix, made sure all of the systems remained functioning and all of the equipment was up to snuff. Afterward, she probably checked on Brogan ten times and put him in she and Ronan's bed once he was asleep, and eventually (after a few hours of maintenance on critical systems that had been damaged/contaminated) joined him.
