Hello Marquand,
Thank you for getting in touch with us.
1/ Unfortunately, no. Brands is a custom post type, a custom one for a particular theme.
2/ It will be necessary to change not only colors, fonts, but also some content on the pages. Unfortunately, Xstore does not have backward compatibility with Royal or other of our themes.
3/ Regular updates that include new demo versions, fixes, and new functionalities. We also provide Elementor support and a wide range of widgets for it, which you can view at https://xstore.8theme.com/#design-elements . Additionally, we offer a wide range of Sale buster options https://xstore.helpscoutdocs.com/article/110-sales-booster , custom optimized wishlist https://youtu.be/ZyjZ-vCx0pE and compare systems, patch systemshttps://xstore.helpscoutdocs.com/article/158-how-to-use-xstore-patcher , header and single product builders, artificial intelligence to help with content creation https://youtu.be/kf5fUK8Wh_4 , and much more https://www.youtube.com/c/8theme/videos
We hope this information is helpful.

8theme team
