Yes, a Kshatriya boy can marry a Jain girl.

From the point of view of Jain Dharma:

• Jain scriptures do not forbid marriage by caste (varna).
• Marriage is treated as a social/householder institution, not a strict religious sacrament.
• What really matters is:

- Ahimsa (non‑violence) – especially vegetarian, non‑addiction lifestyle - Satya, asteya, brahmacharya (faithfulness), aparigraha - Mutual respect and support for the Jain girl’s faith and practice (puja, samayik, festivals, etc.).

Things to think about practically:

• Will the boy accept a strict vegetarian / Jain-style life at home (no meat, eggs, alcohol; often no root vegetables)?
• How will children be brought up – Jain values, rituals, stories, etc.?
• Are both families willing to cooperate peacefully?

So, religiously it is allowed. Any objections usually come from family or social customs, not from Jain philosophy itself.
