All of the schools you’ve listed are incredibly selective. But you have great test scores and grades. It also helps that your parents can pay in full.
I think you have decent chances at all of the schools, but a lot will depend on how many other students from your country are also applying. I agree with the others that a 93% SSAT is fine. No need for anything higher. Retaking it will imply that you are a just a grade-grubber. A difference between a 93% and 99% is meaningless.
Also sign up for any virtual sessions with the admissions offices. Show interest, that can also help.
