Is scrollable Front Page with lots of content possible in Free Version?

Hey Guys, Hope your well, Im wondering is it possible to put all / most of the content you see below the main image on the Home page of the theme demo of Rock Star? Im Hoping to make a simple 1 page scrolling website with the following sections "Bio", Videos, Music and Contact. If so how would I start adding the content below the Large home page image? Lastly, Is it possible to have an email list Sign up form right in the middle of the Main Image on the Home Page? Any help would be greatly appreciated :) All the best, Max
