Hello I’m getting closer and I can finally jum between one categorie into the next but after that it stop. So I’m still not able to loop through all the categories. I hope someone know a trick.
best, Carol
Update Code:

<?php
$prev_post = get_adjacent_post( true, '', true );
$next_post = get_adjacent_post( true, '', false );
$prev_post_id = $prev_post->ID;
$next_post_id = $next_post->ID;
?>

<?php

if(($prev_post_id === '') || ($prev_post_id === null)) :

$query = new WP_Query( array( 'category__in' => array( 2,3,4,1,5 ) ) );

if($query->have_posts()) : while($query->have_posts()) :
    $query->the_post();
    $prev_post_id = get_the_ID();
    endwhile;
endif;

wp_reset_postdata();

endif;

if(($next_post_id === '') || ($next_post_id === null) ) :

$query = new WP_Query( array( 'category__in' => array( 2,3,4,1,5 ) ) );

if($query->have_posts()) : while($query->have_posts()) :
        $query->the_post();
        $next_post_id = get_the_ID();
    endwhile;
endif;

wp_reset_postdata();

endif;
?>

<div id="left">
						<a href="<?php echo get_permalink($prev_post_id); ?>" class="myCursorPrev">&nbsp;</a>
					</div>
					<div id="right">
						<a href="<?php echo get_permalink($next_post_id); ?>" class="myCursorNext">&nbsp;</a>
					</div>
