Hello

Yes, you can fill the JEE Main form even if your father’s name is different on the Aadhaar and 10th marksheet.
Use the name exactly as it appears on your 10th marksheet, since that’s considered official for exams.
Aadhaar is mainly used for identity verification, so a small mismatch won’t cause issues.
Keep the Aadhaar update slip or request number as proof that the correction is in process.
If NTA opens a correction window later, you can update the details then.
Make sure spellings are accurate and consistent across all other details.
