A body has zero velocity and non - zero acceleration. It is possible as at the time when a body thrown upwards is at the top of the height. In that case velocity is zero but acceleration is equal to g.

A body travels with northward velocity but southward acceleration. it is also possible as in case when a body is going with northward velocity but when break is applied acceleration becomes southward.

A body travels with northward velocity and northward acceleration. it is also possible as in case when a body is going with northward velocity and when accelerator is applied. Acceleration becomes northward.

A body travels with constant velocity and a constant non zero acceleration. It is not possible. When there is acceleration, there must be a a change in velocity either in terms of magnitude or direction or both.

A body travels with a constant acceleration and a time varying velocity. It is possible. Time varying velocity represents acceleration.
