Hi,
to add fields in custom module or Joomla articles you can use our content plugin, see docs at
http://docs.easy-profile.com/index.php/article/content-plugin
so in your case you can use something like this: {user name}, email is {user email}, company is {user company}
NOTE: if you use Joomla custom module then remember to enable "Prepare Content" parameter in module options
To reach a user field from PHP you can see doc at
http://docs.easy-profile.com/index.php/article/jsnuser-object
so in your case you can use a PHP code like this:
require_once(JPATH_SITE.'/components/com_jsn/helpers/helper.php');
$user=JsnHelper::getUser();
echo $user->getField('name') . ", email is " . $user->getField('email') . ", company is " . $user->getField('company');
