Very cute!
I don't know most of the plants...but the one in the center (with the mini-barbie and the house with the star) is a diffenbachia, those can get quite large.
The blue-ish colored one (with the bee) I believe is some sort of kalanchoe, it should be fine in that glass for a good long while. You can make a new plant from each 'leaf' of those by just laying the leaf flat on the dirt and giving the end that was attached to the plant a little push down to be sure it touches!
The one behind the house (with the hot-wheels car) is a succulent I believe and will stay small for a long time, but I'm not so sure about the pretty variegated one in the same pot.
Pretty stuff all the way around!
