Kinetic friction is the friction acting upon a moving object. It would be the frictional force against you if you pulled a box across a table.
Static friction is the frictional force needed to overcome to get an object at rest into motion.
No, kinetic friction is the friction an object in motion across a surface experiences.
Static friction is the frictional force an object stationary on a surface experiences.
in nearly all cases static friction is stronger than kinetic friction.
To elaborate, say we place a plate on a table. Sitting there, it experiences static friction, which resists our efforts to move it. Once we overcome that frictional force, the plate begins to move, but now it experiences kinetic friction, a weaker frictional force.
This is why it's harder to get objects moving from a dead stop, but once going it seems easier to make them move faster and faster.

An object's kinetic energy is energy entirely due to its motion. The kinetic energy of an object, at some given speed, is the work needed to accelerate that body from rest to the given speed.
A Reference Point A reference point is needed to determine if an object is in motion.

Yes, an unbalanced force is needed to change the motion of an object.If an unbalanced force does not act on an object it will continue to maintain its state of motion (either in motion or at rest), not considering the effect of frictional force. This is basically Newtons first law of motion.
The kinetic energy of an object is the energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity

The kinetic technology allows the watch to "wind" from the motion in your wrist - no batteries are needed. Both the hands and the markers are illuminated.
