Is it ok to fall asleep during meditation?

If your goal is sleep, drifting off is not a failure. It is a win. Sleep meditations are designed to relax your body and quiet your mind precisely so you can slip into rest, so there is no need to fight it. During daytime practice you might gently aim to stay awake and aware, but at bedtime, letting go is the whole point. StillMind offers practices made specifically for winding down, so falling asleep is welcome.
