It looks like there might be a bit of confusion here! "Star Wars Rebels" is an animated series that takes place between "Star Wars: Episode III - Revenge of the Sith" and "Star Wars: Episode IV - A New Hope." It ran for four seasons from 2014 to 2018.
As of my last knowledge update in October 2021, there isn't a Season 9 or 10 of "Star Wars Rebels," nor has there been an official announcement regarding a continuation of the series beyond its four seasons. However, the Star Wars universe has many other animated and live-action projects in the works, like "The Bad Batch," "Ahsoka," and others.
