Yes, a object can still be accelerating when the speed is zero, a classic example of which is throwing a ball straight up in the air, at the top of its trajectory it has an instantaneous velocity of zero while it is still accelerating towards the ground.
If an object is not accelerating, then one knows for sure that it is moving at a constant speed.
An object is not accelerating when it is moving in a straight line at an unchanging speed (which may be zero).
If the force acting upon an object are balanced then the object must not be accelerating
Acceleration refers to a change in velocity, which can occur even if the speed remains constant. For example, if an object is moving in a circular path at a constant speed, it is still accelerating because its direction is changing constantly. So, it is possible to be accelerating and traveling at a constant speed at the same time.
If an object is not accelerating, it can exist in two other states of motion: constant velocity motion (moving with a steady speed in a straight line) or at rest (not moving at all).
moving
No. A nonzero acceleration means that the velocity is changing, so it can only have a 0 velocity at a single point in time, such as when a ball thrown in the air reaches its peak.
If an object is not accelerating, then one knows for sure that it is moving at a constant speed.
The object is slowed,The object is stopped,The object's motion is reversed.

Not accelerating. It could be stationary or moving at a constant speed.

If the object's speed is changing, or it's not moving in a straight line, then it's accelerating.
If an object is not accelerating, it can exist in two other states of motion: constant velocity motion (moving with a steady speed in a straight line) or at rest (not moving at all).
When a falling object has stopped accelerating, it has reached its terminal velocity. At this point, the force of air resistance acting on the object is equal to the force of gravity pulling it downward, resulting in a balanced force and a constant velocity.
That is possible, for example, if an object moves around in a circle. In this case, the velocity changes all the time; the speed does not.
