a contact force requires two bodies to either touch each other(are in contact) or are interacting through a medium(rope, pole). example of contact force is friction.
When the process that requires energy results in a displacement in the direction of a force, the process is known as work. Work is the product of force and distance.

Yes. The definition of a force is a push or a pull. So, as long as the object moves, a force has indeed acted upon it.
the lines of force are not real. these lines of force are imaginary lines. so we can not touch it.

Red Laser, and it's only for iPhone because it requires the camera.

gravity is the only force that requires contact and cannot act at a distance .

No.
Sliding friction requires more force to overcome its friction.
