I was looking at it. The front looks fairly easy to replace. There is space you can turn the hub on the side away from the dust shield, and have space to work. To put on the new stud, you can put the car in park so the hub won't turn when you are trying to seat the new stud.
For the back wheels, maybe the hand brake can prevent the hub from turning.
Overall, it seems like having 5 lug nuts is more of a safety feature opposed to a mechanical issue being caused by having only 4.
