There is no “right” or “wrong” answer when it comes to how many towels you should have with you. Something that I like to keep in mind is that you will likely want towels for different reasons. For example, a smaller personal towel is excellent for wiping sweat or dirty hands. A larger golf towel is great for cleaning your gear. I would not recommend using the same towel for everything as gear can get pretty messy, and the last thing you want is to wipe said dirt on your face when you’re trying to clear it of sweat.
