Is 4 AP's enough in the context of my school?

My school is a public school that does not allow students to take APs their freshman or sophomore year (sophomores can take AP computer science only if they took the prerequisite computer science course freshman year). They offer in the humanities: APUSH, AP Gov, AP lit and AP lang. In math and science they offer Calc AB and BC and AP bio, AP chem, and APES. The rest of the AP's offered are art based.

I took AP lang my junior year and am taking AP gov, AP lit and APES my senior year. My question is, is this enough for having a chance at an ivy league school or top school like UCLA, Duke, UMich etc.
