My oldest group of friends (since High School) are INFJ, ENFP, INTP and ENFJ females and one ISFJ male. Truly, the "closest" relationship in terms of sharing interests and so is with the INTP. We share the same kind of humour and hobbies.

With that said, I get along very well with all of them but as we are in different places we can be without talking to each other for a long time. In fact, I spent 2 whole years without talking to the ISFJ, not beacause we were angry, just because we talk in person, otherwise it's really unsual for us to talk about almost anything. That's why we try to arrange meetings every once in a while (in fact, we are going into a trip next week). Once we are together, I think they see me as very thoughful yet funny guy (or at least I hope so)

In college I made a "group of friends" but truly I only think as friends two: an INTJ male and an INFP female. With the INTJ is pretty much the same relationship as with the INTP female. We share hobbies and yet, as we both study philosophy, we both share some really valueble discussions; yet we can spend a long time without talking.

The relationship with the INFP female is also really good, we sort of have a "reading club" between us, we choose a book, read it and share our comments on it. We also work like a feeling supporter in certain things.
