Zero rate of change of velocity.
Straight-line motion at a constant speed.
Not with any sensible definition of "acceleration" and "velocity." You CAN accelerate an object and have it end up at zero velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero. Your question is like asking, "Can the value of a quantity change, but also remain the same?"
When a falling object reaches its terminal velocity, its acceleration becomes zero. The downward force of gravity is balanced by the upward force of air resistance, resulting in no overall acceleration.
The acceleration of a vehicle moving with uniform velocity is zero. This is because acceleration is the rate of change of velocity, and if the velocity is constant and not changing, then the acceleration is zero.
When acceleration is zero, the object's velocity can still be changing if the initial velocity is not zero. However, if acceleration is zero and the initial velocity is also zero, then the object's velocity will remain constant.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Zero, by definition.
Certainly! By definition, the acceleration is the change, so it will change unless that amount is zero.
"Stationary" means zero speed. The object's speed is not changing, and the direction of the speed is obviously also not changing.By definition then, acceleration is zero.

Nein. If it's moving, by definition it has non-zero velocity.
The answer is very simple. The words "constant velocity" are the definition of zero acceleration.

No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.

Answer:Yes, but only instantaneously.Consider a thrown ball moving directly upward. At the highest point of its trajectory, the instanataneous velocity (the velocity at that precise instant) is zero even while the acceleration due to gravity remains non zero.
When an objects net force is zero, its acceleration is zero. No force , no acceleration.
I am not sure what you mean by reversing a zero acceleration. An object's acceleration can, of course, change over time.
