using assets from other projects

I’m relatively new to using Unreal 4 (and game development software in general) so I was wondering if there is a way to incorporate specific assets from the ‘ShooterGame’ example such as the HUD, character models and weapons. I only wish to use these temporarily to give my levels more structure rather than using the what is given to you in the first person blueprint (blue arms and blue gun). Thanks for your time!
