I have assumed your friend is also Indian. There is an option now for multiple entry (maximum 30 days each entry) as well as the 15 days single entry (entry cannot be extended)

Thanks for responding. My friend is indian too. As he will not be making any hotel booking bevause he will be staying at my home ,so is there any type of proof or invitation letter i need to give to confirm his stay at my residence.

All the details are available on the website. At the bottom of the web page there are various T&Cs and FAQ detailing requirements specifically relating to applications by Indian citizens using the online service.
