get_post_meta not extracting title,permalink and posttype

Post metas are used for storing custom data that you want to store and retrieve yourself. The default post data post type, title, permalink are not saved in post meta. You can retrieve post_type and title using get_post() function which returns a WP_Post object. For permalink you need to use get_permalink() function like this.

$post = get_post($post_id);
$title = $post->post_title;
$posttype = $post->post_type;
$permalink = get_permalink($post_id);
