which make the relative rotation of two bodies unchanged, but has no 
limits on x and y axises.

IIRC a revolute joint with (0,0) as its "axis" behaves this way.

I believe you meant prismatic joint - yes, it does.

Not exactly.

The no-relative-rotation joint is like the "fix rotation" of a body.
But the "fix rotation" is between a body and the world.
The no-relative-rotation joint is between two bodies.

Many it is not very useful in practice.
