Wind is a non-contact force. But if someone is blowing on an object it would be a contact force because a person is causing the movement of another object.
We can define frictions as the Resistance to the movement of one body in relation to another body with which is in contact. If we try to slide a wooden block across a table then friction acts in the opposite direction to the movement of the block.

Friction is the force that doesn't want two surfaces to move against each other. For example, when you are rubbing the mat, the friction between you and the mat tries to prevent you from moving against the mat. Same with braking.
Physical Pressure, as in press down or against something, is contact.

Yes. Since the direction of the movement changes, that means there is an acceleration. Remember, acceleration is a change in velocity; velocity includes both a magnitude and a direction.Yes.

No. Contact their agent.
movement
Because it is two surfaces rubbing against each other, in this case it creates heat and possibly static electricity. To touch; contact. If two surfaces rub against each other forcefully this is a contact force.
conduction
A mechanical mouse has inside of it a ball which comes in contact with the desktop or mousing surface. As the user moves the mouse around on the desktop, the ball rolls with these movements. This rolling is detected by two wheels at 90 degree angles from each other which are positioned in this way so that one wheel can detect up & down movement, while the other detects left and right movement, together they can reliably detect mouse movement in any direction. A third wheel, the guide wheel is spring loaded and presses the ball against the two sensor wheels.
