Centripetal ("towards the center") force is a real force, that pulls something towards the center during a circular movement. Centrifugal ("center-fleeing") force is a ficticious force, required to explain the observed reactions in a rotating frame of reference.

Gravity
Force of gravity is a pull force. Earth has this force. The earth pulls us towards its center so that we are standing on it. If it was to push we would be in space now.

The gravitational force on a satellite is towards the center of the Earth. The gravitational force IS the centripetal force is this case, so the centripetal force pulls the satellite towards the center of the Earth. There is no balancing force that pulls the satellite outwards (if there were, it wouldn't accelerate, i.e., change direction).

gravity is the force that pulls everything down towards the centre of the earth.
No. Centripetal force is a real force that pulls objects towards the center of the circular motion. Centrifugal force is a ficticious force that seems to pull an object towards the outside.
gravity
A centripetal force is a force that pulls something, that is moving in a circle, towards the center - in other words, keeping it in circular motion.
Air has mass, and gravity pulls anything with mass. The gravity of the earth "pulls" air down towards it's center.
