3 for everything else. Think about it! Assuming you can teleport in any direction as fast as you can think then you can fly, move super fast, dodge any attack, pass through thin barriers (such as fences, thin walls, etc) swim super fast and depending on the rules of this power maybe you can poop really fast by teleporting away but leaving your poop behind!
Plot twist: the act of teleportation is extremely tasking both physically and mentally. Even the most capable persons haven't been able to teleport more than twice a day.
No, you're teleporting, you instantly appear 7 inches away. In the time it takes you to teleporting again, no matter how short, you will start falling and gaining velocity.
