I am working with a Ball & Plate, when using the 6 DOF joint, the ball moves in the Y axis infinitely. What type of joint should I use and with what configuration should it be? to make the ball roll over the plate as it moves and sense its movement.

can you share the mechanics configuration ? It seems you may have the gravity on the Y axis, and the ball simply fall along the y axis because of gravity.
In order to have the ball rolling over the plate you may need to implement a contact force. For older release this is available with file exchange entry:
I would strongly recommend to use the latest release (2020a) where we implemented contact forces natively and take a look at following example. Use a 6 DoF between ball and world, but create a contact force relationship between plate and ball:
