We don’t know you ability or past academic record, so it’s hard to advise on how you will succeed.
My D is currently taking four AP courses as a Junior with no issue and has five planned for next year. She has a strong academic record and work ethic, so I have no concerns over the workload (they are all just natural progressions of her past courses). Her older sister didn’t have the same track record and dropped one of her Junior year APs when it was obvious the workload would be overwhelming.
Your advisor, parents, and teachers would be appropriate advisors, knowing you better and having seen many students over the years.
No college is going to look at 9+ AP courses as less than rigorous.
