Hello Devulapally,
Taking into account the rank that you have scored and that your category is EWS, you should be able to get Chemical Engineering in NIT Warangal under Home State quota.
Some additional information about JEE Mains:
JEE Mains is an annual exam that is conducted by the National Testing Agency and the CBSE for admissions to undergraduate engineering courses in NITs, IIITs, GFTIs and other institutes. It also serves as the first stage for admission to IITs through JEE Advanced.
EWS is a new category that has been created by the MHRD for economically weaker sections. 10% seats will be reserved for those candidates whose annual family income is less than INR 8 lakh per annum.
As for your question, considering your peercentile, you won't be able to get CSE in SASTRA but should be able to get other less preferred branches.
