or just put 3 recommendations combined?
I have a different take on this. 6 is bad, all 3 from 1 school might not be the way to go.
Most colleges only require 2 recommendations and maybe a 3rd from your HS Counselor. I would be very strategic about this and only submit the 2 teachers that know you best and have the highest probability of advocating for you and explaining your narrative. As far as HS counselors, I would pick the one you have the best relationship with who can best explain your academic record if asked to clarify things on the phone or email if need be. Do not submit 6 recommendations under any circumstance.
Good luck
(in the future, avoid asking the same question on here 3 times).
It is honestly up to you, though I wouldn't do too many recommendations. I would choose the recommendations from the teachers who did/do know you best and in classes that are relevant to what you are interested in.
