Jerry- ISTJ- Everything about Jerry screams ISTJ. he goes by protocol, is very neat, and his Te is especially evident in the later seasons. I can see ISFJ or maybe even INFJ in the earlier seasons though when he seemed to have more of a moral compass.
Elaine-ESTJ- Again, in the earlier seasons she seemed more ESFJ as she was into animal rights and morality, but in the later seasons she was presented as an executive and dark hearted control freak.
Kramer- ENTP- the most obvious one, as he always has wacky ideas as his Ne is on full display.
George-INFP/INTP- The hardest to type in my opinion. In the beginning seasons his neuroticism and future anticipation along with his indecisiveness seem very INFP. But in the later seasons he seems more indifferent towards everything.
