1 and 2 are fine, and so is 3.
4 is not used since a cup doesn't have a "face."
1. Place the book upside down on the desk.
2. Place the book face down on the desk.
3. He placed the cup upside down on the table.
4. He placed the cup face down on the table.
(Can we use both expressions together? Is each pair the same in meaning?)
