Is fifteen minutes a good nap length?

Yes — a 10-to-20-minute nap refreshes you without entering deep sleep, so you wake alert rather than groggy. Fifteen minutes sits right in that window. Set an alarm so you do not oversleep into heavier stages.

Can I use it as a study timer?

Absolutely. A 15-minute sprint is short enough to start when you are procrastinating and long enough to make progress. For longer, structured study, a Pomodoro-style 25/5 cycle may suit better.
