The x and y displacement from the origin along standard orthogonal axes
According to http://mathworld.wolfram.com/RadiusVector.html the radius vector (often written as r hat, or the letter r with a carrot ^ over it) is just the distance from the origin to the point of interest. So the magnitude is the distance between the point and the origin, and the direction is the direction from the origin to the point.

It is the one to the lower left of the Origin - or in the South West direction.
In a coordinate system, it represents the distance from the origin in the positive direction of the x-axis.
Those two pieces of information give the displacement vector.
the origin is define as the point (0,0) it means no motion or no displacement
You cannot since the graph shows displacement in the radial direction against time. Information on transverse displacement, and therefore transverse velocity, is not shown. For example, there is no difference in the graph of you're staying still and that of your running around in a circle whose centre is the origin of the graph. In both cases, your displacement from the origin does not change and so the graph is a horizontal line. In the first case the velocity is 0 and in the second it is a constantly changing vector. All that you can find is the component of the velocity in the radial direction and this is the slope of the graph at the point in question.

To obtain the average velocity from a displacement-time graph, you can calculate the slope of the line connecting two points on the graph. Divide the change in displacement by the change in time. To obtain the instantaneous velocity, you need to find the slope of the tangent line at a specific point on the graph. Choose a point on the graph and draw a line tangent to the curve at that point. The slope of this tangent line will give you the instantaneous velocity at that specific point.
Radially, that is in every direction.
That the component of the velocity towards or away from the origin is zero. You can infer nothing at all about its overall velocity since it could be travelling in a transverse direction at any velocity.
Yes, they can be of the same magnitude and direction.
Both have the same displacement, because displacement is the didtance from the starting point, and the batter and the ball are of the same distance from the point of origin.

Depends on your point of origin.
