Hi, I'm not familiar with the Detector / output generated, and the dots kind of confuse me (cos you can join them to make just about any shape in some cases!), but the first two, I would say are Myotis species, strong vertical sweeps, quite rapid, more than 10 a second.
So, either Whiskered, Natterer's or Daubenten's, in that order of likelihood I'm guessing.
3 and 4, no idea.
The last one, I could make out a backwards "J" shaped call with a peak in the mid-30's which could be a Nathusius' running along the top of the spectogram, but again, I'm guessing.
