Agreed.1st is a common nightshade or similar.
3rd looks like a wide leaf plantain.
#2 is a bellflower, possibly Campanula americana. I have those growing wild on my property. DW thought they looked pretty, and transplanted some into her flower garden - BIG MISTAKE!!! They are very invasive and spread like crazy, that was a couple years ago & we are still rooting them out here & there. We did let some grow next to the foundation, where they don't threaten anything else.The purple is some type of Platycondon or bellflower.
