What you see as lightning is air that has been superheated until it glows by an electric charge travelling through it. In a vacuum there is no air, thus no visual.
lightning bolts occur in the clouds.
Conduction cannot occur within a vacuum because it requires a substrate (i.e. matter) for energy to be transferred.
by radiation - convection and conduction cannot occur in a vacuum!

Yes, in general friction can occur in a vacuum, but the only kind of friction that doesn't occur in a vacuum is, of course, air friction. There is no drag force on an object falling in a vacuum.
no
Lightning does occur in different places, but many more times then 2!
If thunder and lightning occur together close to you, you are dangerously close to a lightning bolt.

Since tornadoes occur during thunderstorms they are usually accompanied by lightning, but it does not necessarily occur inside the tornado.
No. While tornadoes and lightning often occur at the same time a tornado cannot be made of lighting, nor are the two directly related. A tornado is a vortex of air; lighting is an electrical discharge.
