How to create a post template with two sidebars

If you add sidebar-sidebaraleatorio.php and sidebar-sidebarrecomenda.php sidebar templates to your (child) theme directory, you can then call them with get_sidebar() function.

Like so get_sidebar('sidebaraleatorio); and get_sidebar('sidebarrecomenda);.

You can read more about sidebars from the Developer Handbook > Sidebars.
