The second is known as lucky bamboo, and will do fine under water for several months, and will do best if the leaves make it out of the water.
The third is anubias barteri var. nana, and can be planted in the substrate, just keep the rhizome close to the surface. They need very little for special requirements. You can look in the sticky 'Plant Profiles' at the anubias barteri.
