Can’t Heimdall see all the Infinity Stones? (And other concerns.) [on hold]

Throughout phase one and phase two, at various points of various movies we are given a little information about three different Infinity Stones — the blue stone (Tesseract) in Captain America, Iron Man and others; the purple/violet stone in Guardians of Galaxy; and the red stone (the Aether) in Thor: The Dark World.

What I want to know is:

• Who is the all-father who supposedly created the six Infinity Stones?


• Where are the rest of the Infinity Stones?


• What happens to the owner of the stones (although a brief example is shown about individual stones in different movies)


• Can't Heimdall see the position of all Infinity Stones, and hence alert the warriors when someone is about to mess around with any of them?
