Bonsai is not a type of tree, it is the art of maintaining any tree in an artistic miniaturized form in a small pot. A large variety of trees and shrubs can be treated as bonsais, anything from pines, firs, oaks and elms, to ficus, cherry, azalea, etc. No one can tell you what your tree needs without knowing what kind of tree it is.
In general trees that grow in cold climates including pine, fir, juniper and deciduous trees like oak, maple etc cannot survive indoors, partly because they require cold winter dormancy.
Tropical trees that are adapted to year around warm temps, often can be grown as indoor trees, but you still need to know what kind of tree it is and what the conditions that tree needs are.
If you don't know what kinds of trees you have, post some pictures here and most likely someone will be able to identify them for you. Then read up on the care of that kind of tree - every tree variety has different needs.
