Be aware, there’s placement and there’s credit. Your DE classes may place you at higher levels but you will still need to earn X number of credits at these schools. So, you likely won’t need to repeat Calc 1,2,3 but you will need to take math classes to fulfill credit requirements.
While the amount of your college work is somewhat unusual, many students at top tier schools enter at advanced levels of math. Google “Harvard Math 55”. It’s likely one of the toughest freshman math courses in the country. I think Stanford also has a class like this.
I agree with others, you will need to raise your ACT score substantially. Also, think over your strategy. Is it you go to one of the five schools you listed or UF and nothing else? There’s nothing wrong with this because you know you’re in at UF. Just be aware that you can readily be rejected by all five schools because they reject over 90% of their applicants.
Going to UF can be a great option. You already know the professors and can build on those relationships (for grad school guidance and letters of recommendations). Hopefully you are already seen as a promising student so you will get more attention and guidance, and research opportunities. You likely will be able to take grad level classes. In other words, you don’t need to graduate in one year despite all your DE credits, stay two or three years. Use the time at UF to become a very strong graduate school candidate, not the youngest or quickest.
