4 is some sort of chickweed/Stellaria.

7 is white campion (Lychnis alba) or a close relative.

6 is an Apocynum, Dogbane
7 looks like Saponaria officinalis, Bouncing Bet.

3 is Lysimachia vulgaris or similar sp..
Agree with missingtheobvious that 4 is chickweed/Stellaria.
Agree with jeanne on 6 and 7.

I think the first is white wood aster

Could #2 be Eupatorium purpureum? The leaves seem a bit off for it, but the flower (and blooming time) is right. Despite the name, it is mostly white, not purple.

Good luck on your quest to find the Spiraea virginiana. It is quite elusive. Here is a recent post about it from an outstanding photographer/nature blogger:

#5 may be Brassica nigra. We get that a lot along river floodplains here.

You guys have been great. I have been able to take your suggestions to confirm many of these. I will maybe post the remaining ones later.

Thanks Again,
Charles
