Hi Aanchal,
You can pick a region of Rajasthan and explore instead of trying to cover few places in this short time.
Udaipur, Jaipur and Jodhpur are closer for you to travel. Or Jaisalmer, Sand dunes and Bikaner would be another option. Here is an article that might help you. https://www.tripoto.com/rajasthan/trips/rajasthan-2873
