I am interested in cbs publication books and i am doing these book (s l loney,irodov,maron,govorov). But do you think it is enough or i should try more books and if so then give me names of that books.

The books that you are doing i.e. Irodov, Maron are very high level books for IIT JEE. The level you are working at is very good enough for prep for IIT-JEE. Keep practising the standard material and you shouldn''t have any problems with the exam.
