Display a post count from a custom metabox selection

Try this code:

function postsCount($meta_value) {
    $args = array(
        'numberposts'   => -1,
        'post_type'        => 'custom_post_type', // set you custom post type
        'meta_key'         => 'project_select',
        'meta_value'       => $meta_value,
    );

    $my_posts = get_posts( $args ); 
    $postsCount = count($my_posts);
    return $postsCount;
}
if ( is_user_logged_in() ) {
    echo postsCount('Draft');
    echo postsCount('Completed');
}

or if you want to get all counts by less code, try this:

function postsCount() {
    if ( !is_user_logged_in() ) {
        return;
    }
    $meta_value_array = array( 'Draft', 'Open', 'Pending', 'Closed', 'Completed');
    $postsCount="<ul>";
    foreach ($meta_value_array as $meta_value) {
        $args = array(
            'numberposts'   => -1,
            'post_type'        => 'custom_post_type', // set you custom post type
            'meta_key'         => 'project_select',
            'meta_value'       => $meta_value,
        );

        $my_posts = get_posts( $args ); 
        $postsCount = count($my_posts);
        $postsCount .= '<li>' .$meta_value. ' ' .$postsCount. '</li>';
    }
    $postsCount .= '</ul>';
    return $postsCount;
}

echo postsCount();
