Some of them appear in EVERY season so I can't help but think they will appear in season 5 as well. It depends if they are available for filming and if the writers plan to use them for something. Plus you included Once Wonderland, which is a different show. So, they may have appeared in every year, but not every season of Once. Plus, they may have upcoming projects and with all the Camelot stuff, who knows if they have the opportunity to return.
