In Jain tradition, the title Acharya is the highest religious authority within a monastic order (Digambar or Shwetambar). There isn’t a well-established, canonically recognized rank called “Panchayas padvi” in the standard hierarchical lists found in Jain scriptures.

If someone uses the term “Panchayas padvi,” it is likely:

• not a standard, widely-attested rank in canonical texts, or
• a regional/sectal nickname for a different position (but not an official rank like Acharya).

So, in general, Acharya would be considered higher in authority than any non-canonical or unclear title such as “Panchayas padvi.” If you have a specific source or manuscript where you saw this term, share it and I can examine it more precisely.
