There really are not any tutorials here on basic template coding for WP.
Once you have that figured out then showing a field only when it has content is simple.
For example:
<strong>PROPRIETARIO:</strong> [acf field="proprietario"]
in PHP becomes
if (get_field('proprietario')) {
?><strong>PROPRIETARIO:</strong> <?php the_field('proprietario'); ?><br />
}
These types of examples for fields can be found in the documentation for each field type.
Another option would be to build your own shortcode. There are a lot of tutorials on the web for how to built custom shortcodes
ShortcodesUltimate has a shortcode creator add on to create shortcodes without messing with theme files https://getshortcodes.com/add-ons/shortcode-creator/
