4 is a male Potanthus ganda. (veins not darkened; no other unsual features.)

10 is correct. T. septentrionis.
I always wonder about this butterfly. The few times I have seen it, the markings appeared more green than blue, but in pics it is always blue.
I even observed one resting with open wings for some time a couple of years back. ( I assured you it is not a mimic.)
