I think they are parlor palm, schefflera, and ficus.
Classic house plants that do well in situations of low light. They don't need much - bright, indirect light, water thoroughly, but not very often, wait until they are drying out a bit, fertilize occasionally. Best thing you can do for them is mist them whenever you think about it, like every day or few days.
I have all of them at home and except for the misting, I pay very little attention to them and they do fine.
