No, you cannot. You ONLY ever keep chinchillas with chinchillas. There are no other animals that can be caged with them and, as far as I am concerned, no other animal should be caged with anything but a cagemate of it's own species. Rabbits with rabbits, chins with chins, etc.
Have you done any research into either chins or gliders? If you have, you'll know that their diets are vastly (and dangerously) different, as well as their caging requirements and environment.
