[MCU] Did Thanos truly require all the Infinity Stones in order to achieve his ultimate goal? What exact power did each one contribute to his final "wish", in particular the Soul and Mind Stones such that he required them all to make it work?

Power Stone - Supplied the raw energy with which to make the Snap happen.

Space Stone - Allowed the effects of his Snap to travel across the entire universe. Note that the other Stones' effects are all localised, apart from this one, which obviously teleports and opens bridges between different points across space.

Reality Stone - Allowed the reality alteration/unmaking that comes with the Snap.  Basically does the hands on stuff regarding the Snap.

Soul Stone - Not confirmed yet, but likely has something to do with the Snap affecting living sapient beings. All creatures with souls. In order to destroy ( or transport, depending on which fan theory you're subscribing to ) beings with souls, the Soul stone's gotta step in to finish the job.

Mind Stone - Needed for the vast calculations that come with eliminating half of all sapient life in the universe. Thanos' own mind is too puny to grasp the numbers and figures involved, so the Mind Stone acts as a sort of guiding supercomputer, directing the powers of the other Stones to do their job.
