Pictures 1, 3 and 4 are a little far away to see the details. I don't know what #2 is.

5. Christmas Fern, Polystichum acrostichoides
6. Maidenhair Fern, likely northern maidenhair: Adiantum pedatum
7. Sensitive Fern, Onoclea sensibilis

#4 Is a Lady fern I believe. I dont know #2 either.

Identification is hard enough with a frond in hand where one can see the sori. With a fern book you should be able to at least distinguish between Dryopteris and Athyrium.

#s 1 & 7 are both Onoclea sensibilis. #2 is a Cystopteris, but not identifiable further. #3 may well be another Cystopteris. On #4 my first guess would be that it's Thelypteris noveboracensis, but nothing approaching certainty is possible from the image.

Check out the Connecticut Botanical Society's webpage, they have some great images of ferns native to your area.

#2 looks like a fragile fern to me.

Thanks for all the help! I have updated my fern page accoding to the suggestions here. If anyone else wants to provide info, I'd be grateful!
Thanks,
Robin
