Just making sure you want to move them on the post edit page. If this is the case, the order that ACF field groups appear among other meta field boxes is not really something that can be controlled. This has to do with the order that the plugins and other things are run on the site.
You can manually drag and drop them into the positions that you want them in and WP will remember the order and show them that way the next time the same edit page is loaded.
