1.

$x = array(
'#type' => 'html_tag',
'#value' => 'hola',
'#tag' => 'div',
);

2.
dpm(drupal_render($x));

See all types

dpm(system_element_info());

for example item_list is not a TYPE but you can use it as THEME

$x = array(
'#theme' => 'item_list',
'#items' => array(1,3,6),
);

dpm(drupal_render($x));

3.

 theme('html_tag', array('element' => array('#value' => $item['title'], '#tag' => 'div', '#attributes' => array('class' => 'cana_image_legend')))
