Mohan, let us first predict your expected rank based on this percentile in JEE PAPER 1.  See,to be honest, it is difficult to predict the exact ranks currently as the April JEE MAINS session has yet to take place and only the best of two scores would be counted in the end. However, you can predict your expected rank by this formula:-


So,(100 - your total percentile score) is the percentageof people ahead of you. Now, 869010 were the number of candidates who appeared for Jan exam. So rank formula is (100 - your total score) X 869010 /100.

If ,however, the number of candidates for April exam get increased to another 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 60830 . Note that it is the expected ALL INDIA RANK and not the category rank or EWS rank which is very difficult to predict at this point of time. Note that the cutoffs for any college also depend on home state considerations and gender status, Now, in your case your chances of getting CSE at NIT WARANGAL would be extremely small as the previous years' cutoff in terms of GENERAL RANK at NIT WARANGAL for CSE course was 2977 for Home state quota students, 2328 for Andhra Quota students and 1980 for All India quota students, so your chances are slim taking the previous years trends into consideration.

HELLO MOHAN
Congratulations for your result and qualifying JEE mains.
since it is very difficult to predict the exact rank but we do have a backup we have a formula to calculate the expected rank that is (100 – Total percentile) x 869010/100.
So according to formula your expected rank for present percentile for January session comes out to be 60917. Now the expected rank might change depending on the no of candidates appearing the april session. For ex if 12 lakh candidate appear the april session then just replace 869010 by 12 lakhs. But if you score above 85 percentile then you have a very decent chance of qualifying jee mains.
Now since the official cutoffs fro college are yet to be decided but let us analyse your chances by looking into the previous year cutoffs data. Since you did not mention your category neither the state you are from so let us assume it to be general.
NIT WARANGAL 2019
AP Chemical Engineering 13523 - 14275 (Andhra pradesh)
HS Computer Science and Engineering 978 -2341
OS Computer Science and Engineering 826 - 1554
since we do not have any formula to calculate the category ranks so this cutoffs are of general category.
After looking into the data it seems a little difficult for you to enter this institute
No worries since you have an april attempt left and most importantly baap of the exams i,e Advance which may directly lead you into IIts.
