So I found the solution: You just insert both templates (made like every normal template for custom post types) and then come to the page-template and do this:
<?php
$args = array( 'post_type' => 'equipa', 'order' => 'ASC' );
$loop = new WP_Query( $args );
$c = 0;
while ( $loop->have_posts() ) : $loop->the_post();
if ($c % 2 == 0) {
include 'template-post-left.php';
} else {
include 'template-post-right.php';
}
$c++ ;
endwhile;
?>
