Hmmm, No3 will be another guess from me but it reminds me of Moss Rose, where I've been a few times with the open away end and a few seats on the side terracing!
No4 reminds me of Arsenal's old ground, Highbury, but I don't think it can be with those small floodlights, so I don't really know!
No5, another guess, but I would definitely say it's lower league, again looking at the floodlights, so I'll take a guess and say Cambridge United's ground!
