How do I access the array of label values in my template file?   

$datas = $view-&gt;style_plugin-&gt;rendered_fields;
print_r($datas);

// Response
// Array ( [0] =&gt; Array ( [field_company_name] =&gt; Google [field_registered_address] =&gt; USA ) )
The field definitions are in a slightly different place, you can extract all labels with something like this:

$labels = array();
foreach ($view-&gt;display['NAME_OF_DISPLAY']-&gt;display_options['fields'] as $definition) {
  $labels[] = empty($definition['label']) ? 'No label' : $definition['label'];
}
