Rest and constant velocity.
Acceleration is changing velocity. Zero velocity means no motion. Zero acceleration means constant, unchanging motion.
For uniform motion, the acceleration is zero. For non-uniform motion, the acceleration is something different than zero - at least, most of the time.
Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.
Uniform motion means "constant speed in a straight line".That's another way of saying "zero acceleration".
Yes. Eg : in case of a uniform circular motion. In general, for every motion in which direction of motion of particle keeps changing continuously and the particle moves with same speed, then the net acceleration is non-zero, although tangential acceleration is zero.

Zero net force has no effect on an object's motion whatsoever.

yes,in case of circular motion .
Zero rate of change of velocity. Straight-line motion at a constant speed.
'Acceleration' means any change in speed or direction of motion.'Uniform' motion means no change in speed or direction.
