can an object have negative acceleration and zero velocity at the same time?

Not if you are using the same point of reference (i.e. the point in space you are comparing the object to) for both its acceleration and velocity.
Pendelum anaysis doesn't work. The only time its at zero velocity is exactly the point where it is experiencing zero acceleration, not negative acceleration

No, if an object has acceleration it cannot of zero velocity. Unless the reference points are different.

No.
Think of it from a math point of view. Acceleration is the change of velocity per unit time (i.e. dervitive of velocity)...
So if a = delta(Velocity)/Time
and the Velocity is 0
then at that moment, a=0

Hi,
Acceleration is a change in speed or direction. If it is in motion then it has velocity, so it can't have both.

Yes. Think about a pendulum at the end of its swing. It is experiencing acceleration but not moving at that instant.
