no pic shows for #1
#2 Podophyllum peltatum aka mayapple
#3? Glechoma hederacea aka gill over the ground
I can't see No.1 either. I agree on No. 3 but No.2 isn't Mayapple. It has a stem with petioled leaves coming off it. Looks like something in the Malvaceae perhaps.
This is pic 1 thanks
Pic 1 Rudbeckia laciniata
Pic 2 is not Mayapple - I have Mayapple in my garden and it does not look like this one.
This one - I don't know its name but I pull it out from my garden whenever one pops up.
