No, you are not allowed to share premium files as assets. If you are using them as part of a game is ok to share the game. You need to specify in the repository that they cannot use the assets on their projects.
Yes, I'm using premium files as part of the game, and those assets are added to the repository. The repository is private at the moment, but possibly I'll make it public at some point, so the source code could be used by everyone. Ok, will add specifications in regards to Licensed assets, that it is prohibited to use them. Thank you very much for the clarification!
