Yes, you can use Premium Layouts with 5.x versions. But, please see;
https://www.primefaces.org/serenity/docs.xhtml

Serenity uses new PrimeFaces Grid CSS (ui-g-*) throughout the samples, we strongly suggest using Grid CSS as your layout framework as it is well tested and supported by PrimeFaces. Grid CSS is automatically included on newer versions however if your PrimeFaces version is older than 5.3.14, add the provided grid.css file under /serenity-layout/css/ folder to your template manually.
