Well, usually you can’t stack need based aid after your need has been met. Many of the schools OP has listed do not meet full need, so it is a good thing to get merit aid and then if there is still need, some of the remaining need can be tackled with the Pell, SEOG, school grants, and finally the loans.
My daughter had 9-10 types of FA, and we just stacked them up as best we could. The order of applying them also mattered and some could only be used for tuition, others for things billed by the school, and some for anything.
