General Layout
The following examples are of the tags which are supposed to be used for the general layout of a typical page in html5. This consists of the <header> , <footer> , <nav> , <article> and <section> elements.
General Layout Example: I'm not a graphic designer so the page is still kinda sucky, but I kinda tried to make what an average real world page could look like with html5 layout.
Web Forms 2
Web forms 2 is part of html5. Actually, the whole process of getting html5 started kinda got started with trying to come up a better way of having web forms, which now is web forms 2. Its only later on that the WHAT-WG built up on it, and started work on html5. Some of the most exciting features are the attributes in the <input> tag, such as the date attribute, which gives you a whole date picker without any JS coding. Also, the email attribute which natively checks on the browser side whether the text is structered as an email address or not. For more info on web forms2, please read my article on it here.
