You can use as many as you want based on my interpretation. In fact, I don't understand why you would think otherwise. The HTML5 spec gives examples at http://www.whatwg.org/specs/web-apps...-aside-element

As long as the correct content is in the element, how it's rendered doesn't matter. I can think of plenty of scenarios where an
element would be a column to the side of an article: a tower ad, a list of related links or facts, graphs, etc. Wouldn't make sense for a general site navigation column though.
