You have already accomplished so much. I think you would be a competitive collage applicant. I would advise that in all these activities that you are doing, and/or in the classes you really enjoy, make sure you are connecting to and forming a report with your teachers, instructors and mentors. Having strong letters of recommendation is as important as good grades and a breadth of extra curricular activities. Other than that, enjoy your time in high and the time you spend with the people with whom you are doing all these activities with.
