I think you should apply to more in-state schools given you have free tuition. The money from parent 1 and your grandparents, combined with a small student loan and possibly part time or summer work can hopefully pay for R/B.
I am not convinced that the other schools will be affordable. The good news is that if they are affordable and you are accepted, you can attend.
I think you will be accepted to Quinnipiac and Pitt, but the issue will be affordability.
Pitt would be a great option for grad school, which you may consider given your major.
