Can I use two <aside> element in one page

HTML & CSS
1

Hi,

I have start exploring HTML5 and CSS3.
I need suggetion for <aside> element.

I have 3 navigation for my page.
For Ex.
<header>
<nav>Primary Nav</nav>
</header>
<aside>
For secondary Nav
</aside>
<section></section>
<aside>For Third Nav </aside>
<footer>Footer</footer>

I feel two <aside> element are not good for use for secondary and Third nav
but not sure.

Please explain if someone has any thoughts about it

Thanks,
