Am I going to reduce a room’s temperature covering a huge hopper window with either paper or reflective aluminum foil, but leaving the window a bit open when the sun shines directly into the window?

Depends, sometimes hot air gets sucked into the room - but in general it probably will improve your situation a bit. Can you also leave a door open to create a draft? If you are lucky you can pull cooler air into the room. Best try. Covering the sun away is always a good idea.
