are 4 years of Science enough for Harvard

Is it true that most of the AP’s that you take should be related to your major, but also taking at least one challenging course in all 4 course areas including Foreign Language?

You should have AP’s balanced across all (or most) core subjects. So you can have several histories, but also need math, science, etc. And no, nobody needs more than 4 years of science for Harvard. There is no expectation that any applicant take all APs offered.
