Ok here are types i'm completely sure about , beware of Spoilers :
Iron Man : ENTP , in his first movie he seems to show Se , but that is actually because of his last Si and his traumatic past.
Dr Strange : INTJ , there have been many types proposed for Strange , but they are mostly based on stereotypes , Strange's materialistic point of view prior to his journey showcase a fixed ideology and a very bad handle on the reality around him which is a last Se problem , his Te is also obvious in they way that he cares about his job and gets it done , the way he wants to keep his perfect record.
Black Panther : ISTJ Obviously
Bruce Banner : INTP
Thor : ESTP , Thor is all about experiencing and shaping his world view based on those experiences (last Ni) , his Ti is obvious in the way he tries to control all the emotions he felt after the loss of his people.
Captain America : ISFJ
Thanos : XNTJ , i need more evidence to determine between First Ni or First Te.
Peter Parker : ESFJ without a doubt.
Rocket : ENTJ
Vision :INFJ
