The darner in flight is definitely not Blue-Eyed; it looks like a Shadow Darner.
I'm not sure what the ovipositing darner is, but I don't think the stripes on the side of the thorax look right for Lake.
The one labelled "Female Common Green Darner" is a male Saffron-Winged Meadowhawk in the process of changing from yellow to red. A handsome one, too -- his black markings are particularly nice and crisp.
The blue skimmer is a male Blue Dasher. Since it's a top view you can't see the color of the face, which is the easiest field mark, but the body shape is different, and Pondhawks don't have that touch of amber at the base of the wing. Also, the way he's tilting his wings forward is a classic Blue Dasher pose.
