Not always, depends on ground and desired floor levels etc.

No you can have DPC `s at different levels, so long as you have a vertical dpc that links the two. Various jobs done where buiding control allowed me to cut into the brick just below the existing so I could tuck in the new dpc to give an overlap. Other jobs they allowed just a vertcal dpc between the old and the new wall.

Not necessarily. It should just be 2 courses of bricks up from ground level.
