[HTACCESS] Multiple URL Segments

[IntactDev]

I'm trying to add a new feature to my TPL system. I want to be able to add the ability to have multiple URL segments, like (profile/Username/Photos). Right now, I can only do one segment (profile/). How can I add more? I'm learning HTACCESS and I took a shot. My TPL system uses the first segment to identify which page to return... but, I now want it to check if the first segment is profile. Here is the pseudo verson:

if(First Segment is == profile) {
check the second segment, and return that page template
} else {
continue code
}

Here is my current HTML:

RewriteEngine On
 
RewriteRule ^(|/)$ index.php?url=$1
RewriteRule ^([a-zA-Z0-9_-]+)(|/)$ index.php?url=$1
 
RewriteRule ^profile/([a-zA-Z0-9_-]+)(|/)$ index.php?url=$1&username=$2

Here is the current PHP:

public function addTpl() {   
        global $zip;
       
        if(!isset($_GET['url']) || empty($_GET['url'])) {
            $_GET['url'] = 'index';
        }
       
        if(file_exists('_zip/_templates/_front/'. $zip['Template']['Front'] . '/')) {
            if(file_exists('_zip/_templates/_front/'. $zip['Template']['Front'] . '/' . secure($_GET['url']) . '.php')) {
                ob_start();
                include('_zip/_templates/_front/'. $zip['Template']['Front'] . '/' . secure($_GET['url']) . '.php');
                $this->tpl .= ob_get_contents();
                ob_end_clean();
            } else {
                die(zipError('File Not Found', 'The file <b>' . secure($_GET['url']) . '</b> could not be found. Please re-check the URL; If you were directed here using a link, please report that link.'));
            }
        } else {
            die(zipError('Template Not Found', 'The template <b>' . $zip['Template']['Front'] . '</b> could not be found. Please check your configuration file for a mistake.'));
        }
    }

How can I go about doing this? I hope this is enough info,

Right now I have something like this in my htaccess

RewriteEngine On
RewriteRule ^index$ index.php [L]
 
 
RewriteEngine On
RewriteBase /
RewriteRule ^index/page/([a-z-0-9]+)/?$ index.php?page=$1 [NC,QSA,L]

It allows you to put localhost/index/page/[num] instead of index.php?page=[num]
Maybe you could get something from this?

What does that [NC,QSA,L] mean?

You'll need to use PHP as well (routing)
