For your reference, you can look into the existing Edit Validate rules from Records Explorer > Data Model > Edit Validate(will list all the existing edit validate rules) and more information can be found here.

as the requirement is kind of specific to your use case, I dont think you will get the exact edit validate rule, any how you can take reference from the existing some validate rules (isletterordigit, pychecklength etc..)
