Nice idea. Here are Jain-inspired boy names with a similar vibe to Parshva, focusing on noble virtues and Jain tradition. I’ve kept them unique and easy to pronounce.

• Parshva (the name you mentioned) — sacred Tirthankara; classic and strong.
• Parshwanath — lord of Parshva, a revered Tirthankar name.
• Suparshva — a Tirthankar; conveys auspiciousness and blessed virtue.
• Ajitnath — “unconquered” or "invincible"; a revered Tirthankar name.
• Shantinath — “lord of peace”; serene and dignified.
• Vasupujya — a Tirthankar; associated with divine nobility.
• Sambhavnath — “one who brings prosperity and growth.”
• Neminath — a Tirthankar; known for compassion and discernment.
• Kunthunath — another ancient Tirthankar; strong, steadfast sound.
• Adinath (Rishabhanath) — the first Tirthankar; foundational and timeless.
• Mahavira — “great hero”; famous and strong, often chosen for its regal feel.
• Ajitabh (less common) — evokes invincibility with a gentle, modern touch.

Notes:

• All of these names carry Jain spiritual resonance, often linked to revered Tirthankaras or Jain virtues.
• If you want to choose between Digambar and Shwetambar usage, Shwetambar and Digambar traditions sometimes favor different historical Tirthankara names; I’ve listed widely recognizable forms that are commonly used across both traditions.
• If you’d like, I can provide exact meanings as found in Jain scriptures for each name, or tailor a short list to a specific starting letter, sound, or meaning (e.g., peace, courage, prosperity).

Would you like me to expand any of these with precise meanings from Jain scriptures or suggest more names starting with a particular letter?
