The plants shown in the first link (zps1acbc847.jpg) included with the question are a Swedish Ivy (Plectranthus verticillatus), with the bright green oval leaves, while the plant at the top of the image is an English ivy (Hedera helix). The waxy leaves of the Swedish Ivy will give off a sweet odor when warmed by natural light, and under ideal conditions, will present sprays of flowers.

The other image is possibly a Peperomia obtusifolia variation. Also, the bits of purple might be leaves from a Wandering Jew (Tradescantia zebrina) plant.
