Formations seem to be a movement keys bound to a key, for my 3 box i bound z to move my main forward one, one alt to strafe left and one to strafe right. For you with 5 characters adding one to move straight back and one not moving would cause a cross formation. Its really not that hard, just go into your keybindings and set a key to each clone to do what you want it to do. As for pause i don't know any key for this, so I can't help you there.
