Will Path.GetRandomFileName generate a unique filename every single time? Also, what about Path.GetTempFileName - will that generate a unique name?

The short answer is yes in both cases.
In reality get it will generate 11 random chars that means there are (26 +10)^11 possible names (1.316217e+17) so chances of creating the same name twice are none existand for all practical purposes.

For more information I suggest you read this

and the relevant MSDN pages

in fact there are only 32^11 possible names because GetRandomFileName() uses base 32 instead of base 36
