Yes, in the Naruto manga, Naruto and Hinata eventually develop romantic feelings for each other and end up together, getting married and starting a family.
The final manga issue shows that Naruto and Hinata have become a couple and had two children.
No, Hinata does not have a demon inside her. In fact, I'm pretty sure that all the demons have been accounted for (in the manga) and Hinata is not a "Jinchurikki" (Host to a demon)
YES!! she professes her love for him in the manga series Naruto and hinata will end up going out cause she confesses in the manga chapter 437
