Thanks a lot, XioaLong & Stone.
1st plant, Seed/Flower pods started blooming and color and shape exactly matched Nicandra physalodes.
2nd plant was Acalypha virginica, it seems. Perfect
3rd Plant : Speedwells seems to be with hairy leaf, right ? this one didnt have any hair. However, we ended up removing it from the garden bed.
Thank you very much for your help in identifying these plants.
