Can ever velocity & acceleration be "0"?

Since both require movement, then technically the answer would be "no".
One can say that they are at zero as an idiom in order to convey the absence of either. Since neither velocity or acceleration of an object are present, then they don't exist. The value given to either of these can be placed at zero for calculation purposes, but velocity and acceleration aren't technically zero in themselves.
Some people here don't seem to understand the difference between assigning a value to a thing and that thing actually being that value.

The saying in the British Army is 'If it's not moving, paint it'.
In other words, before it starts to move and accelerates and gains velocity it's at rest. It has no velocity or acceleration otherwise the Sarn't Major wouldn't be able to make his well-known statement.

Of course. If velocity is 0, then it is not moving so there is no increase in speed=>No acceleration.
What a really silly question. A little thinking would have given you the answer

Newton's first law states that every object is in its state of rest or of uniform motion till a force acts on it.
When there is no force acceleration is zero.
When acceleration is zero the objects velocity may be either zero or constant.
Therfore, velocity and acceleration be zero at the same time,
if there is no force and the object is in the state of rest.
Newton's law is valid in all inertial frame of reference.

This is an obvious answer: when a body at rest then V is zero then acceleration must be zero. Acceleration can be zero when velocity is constant

Velocity and accelerations are relative. So, as you might have understood by now, they can be 0.

Both velocity & acceleration are relative terms.
If the observer is in the same frame of reference then both are zero.
If the observer is moving or accellerating then they may not be considered zero by that observer.

Sure they can. Imagine your car, revving impatiently at the stoplight. There is no velocity or acceleration until the light changes.

Yes, they can be zero. You have to see the event from a suitable frame of reference.
