When to use <nav> tag

As depicted in the flow chart above, a nav tag should be used for major navigational blocks (menus). You may use more than one nav blocks in an HTML5 page but it is better to use it for the primary menu.

When to use <article> tag

An article tag is used to enclose the main contents of the page. This content could be a news article, a blog post, forum post, or even comment on articles or sidebar widgets having a heading.

When to use <figure> tag

The figure tag is mostly use to enclose one or more images, however it can also be used to enclose other graphic elements as well as code samples. A caption of the image is then enclosed within a <figcaption> tag.

When to use <section> tag

You may get confused between the usage of a section and an article tag. However, note that while article tag is used for enclosing main contents of the page, a section tag is used to enclose any sub-content, or a sub-section of a website. For example: A web site’s home page could be split into sections for an introduction, news items and contact information.

When to use <aside> tag

As the name suggests, an aside tag is used for additional content which may not be required to depict the meaning of the main content. For example, an aside can be used for sidebar, comments section, pull-quotes, glossary, advertisements, footnote etc.

When to use <footer> tag

While the flowchart above does not contain the flow for a footer tag, it is still an important tag to be mentioned here. The footer tag is used to enclose the footer of the content. For example a site footer containing the copyright information, credit notes etc. are enclosed in a footer tag.
