That isn't too many. Most colleges require 2 from academic subjects, then if you're submitting a music supplement one from your music teacher as well. Then if you'd like to get one from your organization feel free to do that too.
I asked 4 teachers for recommendations; my guidance counselor said he'd read them then include the best two in my applications. Then I'm getting one from my mentor at my research internship, and if I include a dance supplement one from my dance teacher too.
It's better to have enough on hand than not enough to turn in! But I wouldnt recommend turning in 4 teacher recommendations in academic subjects to colleges; you can get them just don't submit all of them.
Sorry for rambling, but good luck!
