Question

it is possible in straingth line motion a particle having zero speed and a non zero velocity explain​

Answer 1

no, ​a particle in one dimensional motion with zero speed may not have non zero velocity because speed of a body is equal to magnitude of its velocity.

Yes we can have zero acceleration and non zero velocity in case of uniform motion in which an object is moving in straight line with constant speed ,here object has non zero velocity but there is no change in velocity so no acceleration.
