I can't tell if there is a lid on it. If so, it will need very little water. If the top is open, you will need to add water regularly but do not oversaturate the media. The shorter plant looks like a peperomia and they don't require a lot of water, similar to a succulent. The other one looks like a schefflera, but they get tall. Let the soil dry out between watering.
