The 2nd appears to be a Cornus - Dogwood.

First one looks like Garlic Mustard, Alliaria petiolata. A nasty weed, if so. Has probably already bloomed (white 4 petaled flowers) , I think I see seed pods developing.

There are definitely seed pods on the garlic mustard and you don’t want them to finish ripening. Pull them ASAP and bag them to put in the trash, not in the compost or for yard waste recycling. Those look far enough developed so that they may well be viable seed.
