Could you please check and improve my sentences?

Very well! Just a couple of problems with the first line: 'fly in an' should be 'fly at an' and 'festival United States' should be 'festival in the United States' and after the first line 'The main attraction of this festival is the focus on Indian heritage and culture. The rituals of the Rajasthan and Gujarat traditions are to be exibited.' would be better. Also, you should ensure you state what you are referring to when you say 'it' with multiple objects that could potentially be referred to. It could be thought that you are saying the United States weighs 250Kg!
