Hello Shekhar,
Before anything could be said about what colleges you can get on the basis of your score in JEE, you should know that it would be too early to predict anything. The cut off trends tend to change every year and same can be expected for this year as well. However, for your given score, you have a feeble chance to get into a good college, including those you mentioned in the question. But you can try the college predictor for further information about colleges, and about the chances of admission in your desired college:
