Bert: ExFP 7w6-2w3-9w1 so/sx
Mr. Banks: ISTJ 8w9-3w4-6w5 or same tritype with 6w5. His having to be constantly in charge as well as not being able to accept a different perspective could easily be the talk of a 6. With the 8 and 3 in there, he'd be a pretty counterphobic 6. He believes in the bank and in a stable, proper society, not necessarily that he wants to take charge and not show weakness under any circumstances (although that may be the case because of his tritype).
Mrs. Banks: I could see her as ENFJ because of her absentmindedness. 9w1-2w1-6w7, because she is extreeemely conflict-avoidant.
Jane: ESFJ 2w1-6w5-8w9 so/sp
Michael: ISFP 4w3-7w8-9w8
