Here are some simple Jain-friendly baby boy names starting with “Chh” (छ / छ्ह):

1. Chhedan – one who cuts off (karmas / attachments)
2. Chhagan – joyful, happy
3. Chhavin – full of good influence / aura
4. Chhaviraj – king of good impression, punya-prabhav
5. Chhitar – beautifully formed, graceful
6. Chhitij – horizon (limit / maryādā)
7. Chhintu – small, innocent one
8. Chhayan – shade, protection
9. Chhedi / Chedanraj – related to spiritual cutting off of sins
10. Chhavinandan – one who increases good reputation (sat-kīrti)

If you want, I can suggest only purely Jain-scriptural type names (based on Tirthankars, Ganadhars, Acharyas) starting with “Chh” as well.
