The first 2 need very little doing. You can if you have the patience go over them and remove the finished flowers. I never do. If happy they my well seed around for you. If the clumps get too big then it is easy to pull out the offending bits.
The Saxony ones need the same sort of treatment too. Just go over them with a pair of scissors and cut off the dead flowers. Or not, if you are time pressed.
These are so called Mossy Saxifrages by the way,
