Bright, indirect light for the Dracaenas. The Parlor palm wants shade. The Philodendron, and Pothos both like indirect as well, and yes, it is a good thing that you're seeing them getting 'giant' leaves, and thick stems. Sounds like they are happy! The Peace lily can handle low light as well, but mine seem to do better with bright indirect. Good growing!
