Yes, that's possible. You can create a new WP_Query object. Do something like this:
query_posts(array('showposts' => <number_of_pages_to_show>, 'post_parent' => <ID of the parent page>, 'post_type' => 'page'));
while (have_posts()) { the_post();
/* Do whatever you want to do for every page... */
}
wp_reset_query(); // Restore global post data
Addition: There are a lot of other parameters that can be used with query_posts. Some, but unfortunatly not all, are listed here: http://codex.wordpress.org/Template_Tags/query_posts. At least post_parent and more important post_type are not listed there. I dug through the sources of ./wp-include/query.php to find out about these.
