MCU | Known Infinity Stones
Colors aside Im gonna have to disagree with 2 of these.
Yes Loki could control them and get in their their head but I believe that would be the Soul Gem. He touches there heart or “soul” to take them over. If it was the mind stone he could have just Xavieried all the Avengers to do what he wanted.
Power Stone seems legit
For Ronan, I believe that would be the reality gem. Space gem Lets you teleport more or less and control location. Reality gem is super dangerous and difficult to wield without other stones, makes sense it would need multiple individuals to wield it raw. And Ronan brandishes it in his hammer as a blaster. then was going to just touch the planet Nova and destroy it with one tap because that is his will
