I'd also suggest you need to buy a little bit of soluble fertilizer and give at least the Coleus some food, dissolved at half the strength it says on the box. It's very pale and leggy and as greene said might benefit from being closer to the window.
Aloes like it hot and dry. Put it near the window and only water it about every 2 weeks. Oh, and make sure neither of them are getting cold a/c air blowing right on them.
If you'd let us know what part of the world you're living in, that would help us to help you. Fill in your profile with your location, would you please? Changing light conditions with the seasons, relative humidity and other stuff affects even indoor plants.
