Hello,
As per the Information Brochure published by National Testing Agency, the only eligibility criteria for JEE Mains is getting 75% marks or be in Top 20 percentile. And during the percentage calculation, as vaguely as I remember only English marks is compulsory and other subjects considered if their marks are higher. Last Year, at the time of admission in the college, I filled marks in the form, including Painting instead of Maths and I am in college. So you can rest assured as there are no individual minimum marks for JoSAA.
Thanks
