I dont know all the names yet and just watched like 8 episodes but I'll give it a try.
I think Hank is definitly ENP. If it's ENFP or ENTP I am not sure yet and its always hard with fictional characters to pinpoint that down exactly.
His best friend the bold guy, I'ld type esfp or isfp. His best friends wife, I would say ISFJ.
Hank's great love is definitly INFJ. That I am pretty sure off. Her husband Bill (or was it Bob

) it'ld type ISTJ or INTJ.
His little daughter I think INFP and Bill's daughter I would give the ENFJ tag.
According to all this NF tags, I see Hank going into a F direction aswell. I probably would type him to be ENFP at the moment. But it's really hard to tell, I myself havent found a liable method to find out if its ENTP or ENFP with a person, they have too much in common.
What I've seen so far that the term "idea" is something that is used often with Hank. His great love for example said "You like the idea of love".
From that point of view, I am tempted to see him more in the ENTP direction. I think a ENFP would handle things better, his primary goal would be a quest for harmony through Fi and that's something I dont see in Hank.
He is more the spontaneous idea guy, who lives for the moment (linear thinking) as opposed to the F guy, who would consider the consequences of his actions (holistic thinking).
I would say so far ENxP and I guess, because he is a fictional character, one shouldnt look deeper into it, because in the end there will be many real facts and things missing that make up a real person.
Gonna watch episode 9 now, show is just great
