I have trouble with Duskywings and several of your pictures are too dark to ID the markings, but the 3rd and 5th pictures look like Horace's Duskywing.

Horace's vs. Juvenal's is tough especially when they are both flying around that time of year. Horace's usually appear in early May, around May 10 in northern NJ, so that may be a helpful clue. I would say photo 1 is definitely Juvenal's. It was taken on 5/4 and is a highly worn individual which means it's been around a while. The others are tough to call, but 3 and 5 do look like Horace's due to the white spots on the cell end bar.
