All of them are underexposed for the majority of the picture. When enlarged #2 (the one with the aurora borealis) is incredibly out of focus. You need to have a longer shutter speed for these to get the proper amount of light. The sky (which I'm assuming is your focus) in all 3 shots are the only properly exposed sections. #1 is the best in terms of correct exposure.
Theres.. just a lot wrong with all of them.
