Here are some simple Jain boy names starting with the letter “P” (with short meanings):

1. Parshvanath / Parshwanath / Parshva – Name of 23rd Tirthankar Bhagwan.
2. Prabhu – Lord, Bhagwan.

If you tell me if you prefer very traditional Jain names or modern sounding names, I can refine this list further.
