AdRotate appends the advert after your content, if the related posts plugin does that too there is not much I can do to change that order.
You can place the advert using a Shortcode though – That’ll make sure that advert is before the related posts thing.
Surely I can use the shortcode, but I have 4 different sites and more than 600 posts. It will be complicated to put the short code in every one.
I had the same problem with the plugin “Easy social share button” It also inserted social buttons after the related posts. But what I did not know it was a special option in the advanced settings of the plugin where I could change the priority.
So I changed the priority of the “Easy social share buttons” for number 1 and now it appears the first one exactly after the content.
In the settings of the ads and groups of the AdRotate there is also such thing as “priority” but I did not find is there any setting of that?

I also tried to put the line <?php echo adrotate_group(5); ?> directly in the file single.php (as it was written in the settings of the plugin, but it is still appears after the popular post.
Is there a possibility to change the priority of the plugin?

The ‘Weight’ function is a filter where you can give adverts more impressions over others by setting a higher weight. This feature is available to AdRotate Pro users.
Using it won’t make any difference in where the adverts show, so it won’t help you. Your best bet is to find another way to add the adverts to the posts or figure out some way to delay the other plugins so they’re below AdRotates output.
Similar to the priority function you found in the other plugin.
