1.True.
Eg. When a ball is thrown vertically upward at the heighest point its velocity is zero but acceleration is 'g'.
2.False.
Because velocity is speed with direction if there is no speed then there is no velocity.
3.False.
Eg. During uniform circular motion the speed is constant but centripetal acceleration is there which changes the direction of motion i.e. the velocity
4.False.
No its not compulsory if the direction of the acceleration is taken as positive but the object is moving in opposite direction in this case the acceleration is +ve but the speed or velocity is decreasing.
5.For this part see the photo
