1.. Ya displacement be zero even when distance is not zero. Take example when a body moves in circular path and reach to point from where it started. Then initial position is equal to final position. Hence shortest distance between initial point and final point(displacement) =0 and distance =2*pi *r.
2..We can get speed of body from its distance time graph by:
Speed is slope in distance time graph. Slope is just tan theta. If graph have rectangular shape then slope is 0.If it is triangular the slope = perpendicular / Base.
3..We can get the distance from speed time graph by:
Area under speed time graph is distance travelled by body.
4..Yes it's possible that if a body have zero velocity but it have acceleration. Think if u throw a ball upward then it's final velocity (at the top) =0 . but it have acceleration downward 9.8ms^-2.
5..If a body is in straight line motion then it can't be possible.
