Not clear what you're after.
Are you saying a single LED indicator that can change its value between 1,2,3,4,5,6? In which case a so-called 7-segment LED display can be configured to do so.
Or are you saying you saying six independent LED indicators which can be all on, none on, or any combination? In which case you need numbered lenses that can be back-lit by an LED.
Perhaps a bit more detail on how you see this being used might spawn additional ideas.
