If they were a sentai team:
Far left is the pink ranger
The girl next to her with her hand on her shoulder is the red ranger and the leader
Girl on her right is the blue ranger. She's sorta a loose cannon but gets the job done
Fitness girl on the far right is the yellow ranger, she's the muscle.
Crazy girl is green ranger. She used to be an enemy, but then they convinced her to join them with some nice steak
