IIT Ropar - Indian Institute of Technology

All the Indian institute of technology that you have listed are good. But among them IIT Varanasi is best. It ranks higher among them. IIT Jodhpur and IIT gandhinagar are both new IIT's and they are also good in term of opportunities and placements that they will provide you. If you got a chance then choose IIT Varanasi.
