It’s possible that your first specimen is a blue dasher (Pachydiplax longipennis) -
The second one does look very much like a slaty skimmer; the eastern pondhawk can appear quite similar, but in that species, you would see a couple of tiny white objects at the tip of its abdomen.
The third one might also be a slaty skimmer, but the image is none to clear…
