Answer 1

I found the right way to do it. It solved my problem. to get other fields to display like company url

<p>Website: <?php echo get_post_meta($post->ID, '_portfolio_url', true); ?></p>

to show featured thumbnail option

'support' => array('title', 'editor','thumbnail', 'custom-fields','trackbacks','post-formats', 'page-attributes', 'comments'),

should be

'supports' => array('title', 'editor','thumbnail', 'custom-fields','trackbacks','post-formats', 'page-attributes', 'comments'),

mistake was support which should be supports.

Answer 2

Have you looked at this documentation? It looks like you need to use the_meta() or another one of the supported tags.
