I've experienced 2,3,4,5,7,10,12,13, but most come and go. 5 is more me not getting burnt as easy, even by boiling water at times. I started a thread touching on some of these which are closely related to the body's core functions like temperature control, heart beat, etc.
One of the easier ones to grasp my be your baser body functions. Once the subconscious has rationalized how best to process this information, it can do some crazy things.
Visualize a warm ball in your stomach, your hands surround this ball keeping it warm, this heat is building and traveling to the rest your body. You can also move your hands in your mind to cause friction on the ball. You can also do cooling, numbing and many others. As these are functions the body does naturally and once you access them the others become easier.
I mention this because most of this is interconnected and the baser body functions is where I would look.
A cool site that talks about a lot of this.
