Common Blue and Large Red-eyed Damselflies.

These are mostly Common Blue Damselflies, Enallagma cyathigerum, as John has said (with a mix of males and females).

The larger damselfly with the dark upper thorax is a male Large Red-eyed Damselfly, Erythromma najas, rather than a Large Red Damselfly, Pyrhosomma, though. Pyrhosomma show complete pale antehumeral stripes on top of the thorax, and have dark markings on the segments at the tip of the abdomen (unlike the pale segments seen here, which will be blue once the damselfly is mature).
