hi friend,
1).yes,displacement can be zero even when distance is not zero
example :- when a body travels in circular path , after covering a circle the distance cannot be zero,but its displacement is zero..
2).by finding the slope of distance time graph,we can find the speed of the body.
3).by finding the integrating of speed time graph ,we can find the distance.
4).yes,a body can have zero velocity and still acceleration.
example- in vertically upward projected body,at its highest point,the velocity becomes zero but still acceleration due to gravity acts on it
5).no its not possible ..when the speed is zero..its velocity will be zero
I hope this will help u ;)

Q1) Can displacement be zero even when distance is not zero? Give example.
A1) Yes , displacement can be zero even if a body has covered some distance. For example , consider two points A and B 1km far from each other, if a body travels from A to B and comes back to A , its distance will be (1+1) km while its displacement will be 0 , because object is back to its initial position.
Q2) How can you get speed of an object from its distance time graph ?
A2)We can get speed from distance time graph by finding the slope of d-t graph using the Pythagorean theorem.
Q3) How can you get distance of an object from its speed time graph ?
A3) We can get distance of an object from its speed time graph by calculating the area covered under the graph.
Q4) Can a body has zero velocity and still acceleration? Give example.
A4) Yes , a body can have 0 velocity but still acceleration but temporarily not it's not permanent.
Example - Consider a body 'A' thrown vertically upwards , at highest point its velocity is 0 , but acceleration due to gravity(9.8 m/s²) still acts on it.
Q5) Is it possible in straight line motion of particle having zero speed and a non zero velocity? Explain .
A5) No , it is not possible in straight line motion of particle having 0 speed and non-zero velocity because when speed is 0 , no distance will be covered by the body and displacement will also be 0 , Hence velocity will also be 0.
