The velocity of the body does not change.
When a body has constant velocity, the acceleration is zero. This is because acceleration is the rate at which velocity changes, so if velocity is constant, there is no change and hence no acceleration.
No, a body cannot have acceleration when it is momentarily at rest. Acceleration is the rate of change of velocity over time, so if the body is at rest, its velocity is zero, and therefore its acceleration is zero as well.
Yes, a body can be in motion but have zero acceleration if it is moving at a constant speed in a straight line. Acceleration measures the rate of change of velocity, so if velocity is constant, acceleration is zero even though the body is in motion.
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.
Yes, but only for an instant. For example, if you throw a stone up, when it is at its highest point it has a velocity of zero, but its acceleration is -9.8 m/s2. If there is acceleration, the velocity can not remain at zero.
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.

zero
Zero.
Acceleration becomes zero.
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
Zero
Zero
I am not sure what you mean by reversing a zero acceleration. An object's acceleration can, of course, change over time.
