OSU is a very good university. Being in-state it should be a bargain. If it really is a safety (you and your guidance counselor would know better than I) then it is a great safety – which is the first place to start in university admissions.
Are you sure that the University of Washington is a safety? Your high school GPA is great (assuming that it is unweighted), but you are out of state and it is quite competitive for out of state students.
I would think that Caltech would be very unlikely partly because of your college GPA and partly because of your math score on the ACT. Caltech has a lot of students who got an easy 800 on the math part of the SAT, and they still find it to be a very challenging university.
