Picture 1 is Impatiens, a shade-loving annual
Picture 2 is a variety of Syngonium...a low-light houseplant, pretty tough, many different varieties available. Roots easily from cuttings whenever it gets too leggy and has to be cut back.
Picture 3...not sure. Looks like the leaves you are showing may not be fully formed. I'll leave this one for some other ivy expert.
