Yes, you can. The only catch is the place that you are claiming rent for can't be owned by you. If you are living with your parents and the house is in their name, and you pay them rent, you can still claim HRA. This does not mean you can simply claim that you are paying them money for rent, you need to have authentic rent receipts and also bank records that show monthly transactions for the same amount. If the tax department does not think that the claim is authentic, you could get into trouble.
