MB Admin Column : Could i change default "Title" with another word

Unfortunately, it's not supported. The plugin is made for working with custom fields and should handle custom columns for custom field only. For the default WP columns, I made it support replacing them only.

However, you can do that with a simple code like this:

add_filter('manage_edit-POST_TYPE_columns', 'prefix_custom_columns');
function prefix_custom_columns( $columns ) {
    $columns['title'] = __( 'Lecture Name', 'textdomain' );
    return $columns;
}
