Here are Jain names that begin with “Ch” (commonly used in Jain tradition):

• Chandraprabha: the 8th Tirthankar in the Digambar and Svetambar traditions.

If you had a specific category in mind (e.g., Tirthankaras, monks, deities, or lay names) or a particular tradition (Digambar or Svetambar), tell me and I’ll tailor the list accordingly.
