Here are some Jain-friendly baby names starting with C (for boy or girl), with simple meanings:

Unisex / Traditionally Jain-related

• Chandraprabha – “moon-like radiance”; name of the 8th Tirthankar (more often used for boys, but also as a modern unisex name).
• Chandra – moon; calm, cool, peaceful.

Girls

• Charvi – beautiful, charming.
• Chhavi – radiance, reflection.
• Chandni – moonlight.
• Champa – a fragrant flower; very common in Jain families.
• Charita – good conduct, virtuous life.
• Chaitali – related to the month Chaitra; springtime, freshness.

Boys

• Chaitanya – consciousness, spiritual awareness.
• Chetan – conscious, aware; used in many Jain families.
• Chirag – lamp, light.

All these are Sanskrit-based names commonly used in Jain families. If you want a strongly Jain-scriptural connection, Chandraprabha (boy) is the most directly tied to a Tirthankar.
