Yep, you sure can. Here’s how:
You can set your default Facebook Page ID on the Custom Facebook Feed settings page within the WordPress admin, you can then define different page IDs in the shortcodes you use to show multiple feeds from different Facebook pages. Just use the id option in your shortcode like so: [custom-facebook-feed id=another_page_id]. You can use as many shortcodes as you like with as many different IDs as you like.
PHP Standalone Version
You can set you default Facebook Page ID within the
fbfeed-settings.php file, you can then pass other Page IDs into the
fbFeed() function to show multiple feeds from different Facebook pages, like so:
$custom = array( 'id' => '171662759544449', ); fbFeed($settings, $custom);
