why do (most) dice have the same face placements? As in, why is the 6 usually opposite to the 1, likewise with the 3 and 4? Does this affect the “fairness” of a dice roll, making it a 1/6 chance every roll as opposed to a different value?

Answer 1

On 6 sided die, the opposing numbers add up to 7
You have 1-6, 2-5, and 3-4. This is just a convention, to make the dices uniform wherever you emcounter them; though it makes it easier to check if they’re not incorrectly labelled, having two sides of 5 or 6.
Plus, 7 is regarded as a lucky number
