Abhishek, the percentile that you have secured in JEE MAINS is the actual NTA score for the JANUARY JEE MAINS session. It is not the average over all the sections of the exam, rather it is the percentage of people from whom you have performed better in the Jan session. So, after getting the score , the next step is to calculate the rank. Now, it is difficult to predict the exact ranks currently as the April session has yet to take place. However, you can predict your expected rank by this formula:-

(100 - your total score) X 869010 /100. However, If the number of candidates for April exam get increased to any number, say, 1200000 then your final rank shall be (100 - your total score) X 1200000/100

In your case the rank comes out to be around 5,90,926. This is the expected All India Rank.

Now, at this rank getting any college will be very difficult and you would probably not clear the cutoffs. However, you have another attempt to go in the April JEE MAINS and I would advise you to concentrate on that.

Also,if you still want to predict your colleges,  you can use this college predictor to know what colleges you would get based on these January scores https://engineering.careers360.com/jee-main-college-predictor
