At ghe moment if I bank right and the right aileron goes up so does the right v tail surface, is that right?

For elevator both v tail surfaces move up for up and Down for down. For rudder the both go in different directions.
If you're trying for the equivalent of an aileron-rudder mix, you want them opposite. Right aileron goes up, right wing down. You want a bit of right yaw, so right ruddervator has to go down/right, and left ruddervator up/right. Pitch forces cancel out, leaving a right yaw force.

If you were thinking trying to use the v tail to assist roll, ie moving in the same sense as the ailerons, I expect you'd get some pretty nasty adverse yaw.
