Can you use on the stationary door of a sliding glass door?

No, not designed to lock in a sliding panel on a glass door

Is one lock sufficient for one sliding window?

Yes one lock is sufficient. For me and mine sufficient isn’t good enough, I put on the bottom and one on the top, don’t make anything easier for the bad guys. Good luck.

Will they work on sliding doors as well?

Hello, please measure your sliding doors track size,Width needs less than 0.59inch (1.5cm),Height needs more than 0.55 inch(1.4cm) ,Please watch the video measurement. If this lock is not suitable for your track, I recommend another lock for you. Please see if the product introduction is suitable for you. I hope to help you, thank you! https://www.amazon.com/dp/B0B54VR2ZF
