Please can you accept these alternate answers: "Signal Iduna" for number 2, and "Nou Camp" for number 4.
And "Allianz" and "Olympiastadion" for number 6. This last one, I tried both and didn't get the point for it (the first two, I did, eventually but believe these are what the stadiums are commonly known as).
