let's see,..the desk first from the left must be ikazuchi's and the second from the right must be inazuma's. no idea for the other two.
I'm gonna go with this (left to right):
First Desk: Ze daughter's. Because Akatsuki always wants to be a lady and most likely thinks a lady is to be in love. Second Desk: It's a toss up between Hibiki and Ikazuchi. Hibiki always got me as the studious type, always on time and perfect with her assignments. But I reckon her true desk is number four. Third Desk: Inazuma. Fourth Desk: See second desk conjecture.
