How mane six save these people??

Rainbow Dash and Fluttershy fly down to save them, Twilight uses her magic, Pinkie Pie uses her logic defying powers to save a few of them, and Applejack and Rarity are too busy fighting each other to save anyone.

RD flies up and catches a few, Twi uses her magic to levitate the plane to land safely, Pinkie, AJ, and Rarity go up in Pinkie's hot air balloon, where AJ lassos them to safety. There. Rarity was holding the rope. Meh.
