From the thumb to the index:



Super launch star (time)

Unira (power)

screwattack (space)

Black hole (reality)

And the index is Zelda (soul)



The mind stone is smash ball.



It's a bit difficult to see the images as samus hand is not facing up so the images are upside down as a result.



All the images including zelda's face were photoshopped, I had a element of free rein in this given I wanted to pick some symbols that looked more serious or significant regardless if the powerup was weak or otherwise.



Zelda was the exception as I photoshopped her head in the soul stone implying a life was given for the stone.
