Hey Sejal,

Congratulations for your result in JEE MAIN. Regarding this, I would like to suggest you to get admission in your State Government Colleges and private colleges through state level counselling procedure like Punjab, Haryana, Rajasthan, Uttarakhand, Bihar etc. Because according to your rank and percentile in JEE MAIN , it's quite impossible to get chance in any kind of NITs and IIITs. You can also check previous year's JEE MAIN cut-off details of NITs for ensuring my assumption through the link provided below:

However, you can also predict your opportunities in JOSSA and State Level Counselling as per your rank and percentile through Careers360  college predictor tool :
