I also thought Cawley was an xNFJ, the F is really quite obvious. I don't know about Andrew, his perception was really much too clouded to really make an judgment on that, but IxTP is a distinct possibility. Chuck is hard to type, as Ivy explained, but he seems extroverted. I'd say perhaps ENFJ. I agree with FalseHeart on the Naehring as an INTJ, but he could also be INTP.
