Hi

I am extremely sorry to tell you dear but you cannot get into NIT

This is because,

With 64 percentile in JEE mains you have failed to qualify JEE mains as you belong to general  category and qualifying cut off percentile for general category is 90.3765335 percentile

As you have not qualified JEE main, you are not eligible for josaa counselling and thus cannot get into NIT

You can go for state counselling and to check the college you can get, you can go through our college predictor, the link for the same is given below

Thank you
