Zero acceleration means that the velocity doesn't change. It doesn't mean that there is no velocity.
Yes, an object can be moving at a constant velocity (i.e., moving with no acceleration) and have a net force of zero. This occurs when the forces acting on the object are balanced, such as when an object is in equilibrium.
Acceleration just means that something is getting faster at a constant pace. If the object was at rest it would have a constant velocity. If the object was then acted upon by and unbalanced force, the velocity would change and no longer be constant. However if an object is just moving along (balanced force of air resistance, gravity, and friction) then it would be at a constant velocity, also. In motion or at rest and object can have zero acceration.
yes
When an object slows down it is still accelerating.
Acceleration doesn't mean "speeding up". It only means that the speed or direction of motion, or both, are changing. Speeding up is positive acceleration in the direction you're moving. Slowing down is negative acceleration in the direction you're moving, or positive acceleration in the opposite direction.

i am ten so this will be a wimpy answer. it is an object that has nothing to propel it and therefor it has no acceleration. see wimpy Actually the above is wrong because an object can still be moving but it is accelerating only when there is a change in speed or direction. A car moving at a constant speed of 50 m/h is not accelerating however we can agree that it is still moving.
it can be moving at constant velocity or staying still

yes
When the forces on an object add up to zero, the object's acceleration is zero. Thatmeans the speed or direction of its motion doesn't change. It does not mean thatthe object isn't moving. A moving object would just keep moving at a constantspeed in a straight line.

No, an object cannot be in equilibrium if it is moving. Equilibrium is a state where the net forces acting on an object are balanced and there is no acceleration. If an object is moving, there must be an unbalanced force acting on it causing its motion.
Yes, it can happen. when the velocity is momentarily zero while an object is changing from moving in the positive direction motion to the negative direction; the object obviously will stop at one point, but will still have a constant acceleration.
An object can have zero net force but still be in motion if it is moving at a constant velocity. In this case, the forces acting on the object are balanced, resulting in no acceleration. For example, an object traveling at a constant speed on a frictionless surface would have zero net force acting on it.
Yes, but only at one instant. For instance, if you throw an object straight up, when it reaches the highest point its instantaneous speed is zero, but of course its speed is changing - thus, acceleration is non-zero.
