I know, that I can print a field from current node in template by e.g.
<?php print render($field['title_field']); ?>
but how I can print another nodes field?
First get that node id somehow, then load whole node:
$node = node_load($nid);
Inside that $node object you'll have your field value. print_r or var_dump $node to see exact structure and how to approach your field value.
