Type my cousin, please

[CautiousWriter]

I was wondering about My cousins type. We are very close, basically like best friends and I like him a lot.
He is male and 18 years old.
Im inclined to type him as INFJ, but ISFJ and ENFJ are also good possibilities IMO.
He did an MBTI online test (16 personalities) which resulted in INFJ.
