Yes, 5 a.m. should be OK, but remember that the tube doesn't start operating until about 5:30 a.m., so if you're staying in Central London, it'll take you about 45 minutes to an hour to get to Southfields tube station (which is where you start your 15-minute walk to the outdoor parking lot/field where you start the queue). I've arrived at around 7 a.m. and it's still fine, just don't let the size of the queue frighten you into thinking you won't get a good seat, as you probably will....
There'll be hundreds of people already in a queue who've camped overnight on the road leading to the front entrance. They'll get in first, but those who arrive very early that morning will also get in...the queue looks enormous (you're herded into the big grass field I mentioned to the back of the queue) and doesn't move for quite a while until they open the front gates at about 10 or 10:30. It's a good idea to bring a newspaper or book to read while you wait, and don't forget to bring a hat/sunglasses/sunscreen if it's sunny, because you'll be standing/sitting there for hours before the gates open. Then, it moves very quickly!
