No need to change what you call freeze plugs, (they are actually casting plugs), unless they are leaking. To replace on simply drain the radiator to below the level of the plug. Drive a chisel into the middle of the plug. Pry sideways to remove it. Clean the area throughly. Install the new plug, by inserting it and hitting it dead center with a plastic or brass hammer.
NO it is not. But you do need to change the oil and filter.
The freezing point of mercury is -38,829 0C.
The two changes of state involved in freeze drying are melting and freezing.

The heads themselves have NO freeze plugs in them. But the block/engine has 8 freeze plugs in it.
Because it does not freeze or evaporate
Engine oil is not going to freeze in your engine. It will get very thick but will not freeze.
Yes, mercury (Hg) freezes at about -39 degrees Celsius (-38 Fahrenheit)
On the night side, yes.
With the freeze plug out it will be impossible to keep water and coolant in the engine as it will all leak out through the freeze plug hole. The engine will over heat and self destruct after a while.
At lower temperatures water will freeze and mercury will not.
It is not necessary to freeze mercury for storage.
