Here are some Jain-friendly girl names starting with the letter “C”, commonly used in Jain families:

1. Charvi – सुंदर, आकर्षक, सुन्दर स्वभाव वाली (beautiful, charming)
2. Chhavi – आभा, तेज, प्रतिमा (radiance, reflection)
3. Chandni – चांदनी, चंद्रमा की शीतल रोशनी (moonlight)
4. Champa – चंपा का पुष्प, सुगंधित फूल (a fragrant flower)
5. Chitra – चित्र समान सुन्दर, स्पष्ट, रोचक (bright, picture-like, clear)

These are Sanskrit‑based names and are very common among Jain girls, though they are not limited only to Jains. They are not tied to any Digambar / Shwetambar difference; both traditions use such names freely.

If you want only those names that come directly in Jain stories or connected to Jain dev-devi (like Cellaṇā/Chelna, etc.), say so and we can refine the list.
