Honestly, jumping between the towers may be the least scary part of the climb. This is not typical rock climbing with anchor point every 2m or so... there are rules in place that state they cannot be closer than 5m from each other and most paths have max 2 (one in the middle and one on top, sometimes only the one on top).

Nope, different rocks.

Those are different ones. These are about 100km to the east from Elbe on Polish border.

Climbing on those things is one of the most amazing and surreal experiences a climber can do. Especially if the ring to belay down from is on the neighbouring tower only...
