Show content by using tags

in case someone else in searching for this, I used a WP Query with the statement tag:

$args = array (myargs1,....,myargsn);
for ($i=0; $i<count($args);$i++){
$query = new WP_Query( array( 'tag' => $args[$i] ) );

…and so on with if have_posts() and a while loop, you can find the whole syntax on wordpress.org, only thing i did working with a for-loop to run run my array
