Claim hra and emi

Hi I am a central govt employee recently posted in Jaipur. I have a query regarding HRA and HOME LOAN INTEREST. The thing is, I have 2 house properties in two different cities and both of them are are taken on loan from banks. One is in Lucknow, which is given on rent and the other is in Jaipur which is also given on rent. I live in jaipur in a rented accomodation and am not able to live in my own house due to reason of my grand daughter' school who lives with us. There are no schools nearby the house which i have bought and also its sort of disconnected from the market and daily essentials as its newly built in a area which is yet to develope. Now, I want to know whether i can claim both, the HRA and Home loan interest benefit (of the jaipur house) as i have been told by few people that both of them can be claimed under few circumstances even if both are in regards to same city.
