OK, so 2 = morrissi no doubt, 1 seems to be chalybata, but still the antenna seems too long (better pic might help / are you very sure it is the same specimen ?)
3 is challinging. It is neither of two above nor fuscipes. According to Rozkosny in Fauna Entomologica Scandinavica, you don't have geniculata and he mentions that the vertex in nigra (as strobli) is slightly narrower than in chalybata. If you check the hind legs, there are indications of dark rings. So, I am still a bit confused, but that is what is should be, I guess.

Check the leg colouration for yourself, I'd say.
