Given that the OP is a Questbridge applicant, needs lots of FA, AND because getting into good UC’s is so difficult these days, unless you are a the first in your family to go to college[ plus one application is all that’s needed for the UC system] , I think his list is realistic .
Yes he will get rejected to a lot of top tier colleges- most do- but all he needs is one college on that list to say yes, and given his profile, I think he has an excellent chance of that happening.
