From my personal experience of taking 5 AP classes in senior year, I’d say it’s definitely manageable, but definitely a pain in the butt. I wouldn’t suggest taking AP Calc as well as AP Stats in the same year, but perhaps math is your thing.
You have yet to know how many colleges you’ll be applying to, and I definitely think the quality of your college essays may suffer due to your workload. However, if you find these AP’s interesting and enjoy challenging classes, go for it! It’s been done before, and can be done again. Just evaluate the motive behind taking so many AP classes, and if you’re truly still a freshman, trust me when I say that senior year will be very stressful rather than enjoyable with this plan in mind. While everyone enjoys senior year and makes memories together, you’ll have to turn down plans and spend hours working at your desk, and once you finally catch your breath and you’re ready to spend time with your dear friends, you’ll be off to college. Are these sacrifices you’re willing to make? Best of luck OP.
