Hi
You cannot change individual cogs, You need to replace the entire cassette. I think your set up can handle extra three teeth without problems. Just may need to tune the rear deralieur. Cassettes are not expensive.
Your photo shows a MB but 25T is short for MB so you must be doing a RB. Some info on bike is always helpful. On a MB you can put a smaller granny gear.
