Here are some simple and beautiful Jain-friendly girl names starting with “Y” and their meanings:

1. Yashvi / Yashvee – प्रसिद्धि वाली, शुभ यश पाने वाली (one who has fame and good reputation)
2. Yashasvi – सफल और सम्मानित (glorious, successful, respected)
3. Yashika – पूजा / आराधना करने वाली, यश से पूर्ण (one who worships; full of fame)
4. Yogita – योगयुक्त, आत्मिक अनुशासन वाली (spiritually disciplined, one connected with yoga)
5. Yogini – साध्वी स्त्री, योग का अभ्यास करने वाली (a female ascetic or practitioner of yoga)
6. Yamini – रात्रि, शांति देने वाली (night; symbol of calmness)
7. Yukti – सही समझ, सद्बुद्धि, उपाय (right understanding, intelligence, wise method)
8. Yashoda / Yashodha – यश देने वाली (giver of fame, one who brings good name)
9. Yashita – जिसकी प्रशंसा हो, विजयी (one who is praised, victorious)
10. Yamini Rekha – रात्रि की रेखा, सौम्य और शांत स्वभाव (line of the night; gentle and peaceful nature)

Jain families usually prefer names that reflect:

• अहिंसा (non-violence)
• सत्य (truth)
• संयम / तप (self-control, austerity)
• शांति (peace)
• सद्गुण (good virtues)

So names like Yashvi, Yashasvi, Yogita, Yukti fit very well with Jain values.

If you tell me:

• language preference (Hindi / Gujarati / English style), and
• if you want very traditional or modern-sounding names,

I can suggest a more focused short list for you.
