One well-known Jain bhashya (commentary) with a 5-letter name is "Tika." However, "Tika" has only 4 letters. Most famous Jain bhashyas, such as "Vritti," "Tika," or "Tatparya," do not have a 5-letter name in the traditional sense.

If you are looking for a specific bhashya name with exactly 5 letters, please provide more context or clarify your request, as it is uncommon in Jain literature.
