You don't "resist" it but you "reduce" it. For example, many vehicles and projectiles are made in a streamline design to reduce air resistance.
Friction. Air Resistance or Water Resistance, depending on where you are and what your doing.
Air Resistance is a force.
No, Air resistance can be considered as a type of friction however, friction itself is considered to be the a force which opposes motion between two surfaces/substances. For example, A train travelling with a driving force of 500N Has 50N of air resistance acting on it and 75N of friction from the rails. They are considered to be separate.

yes it is a big diff in both of them air resistanceis in water butfrictionis every where

An example of fluid friction is the air resistance felt by an airplane.
Wind resistance is a specific example of air resistance. Wind resistance would be a resistance to motion cause by a wind, for example when you try walking forward on a very windy day it is hard, that force preventing you from walking is wind resistance.

How molecules in the air cause air resistance?
There are two factors that influence air resistance with temperature. Air density decreases with temperature so that the force needed to push the air out of the way is decreased, thereby decreasing resistance. Conversely, air viscosity increases with temperature (unlike oil for example where viscosity decreases with temperature) so that the drag increases. Under normal conditions, the density change of air has the greatest effect and air resistance decreases at higher temperatures.
