[MCU] We've seen what happens to mere mortals who come in direct contact with the Power Stone. What would happen with each of the other stones if I grabbed them with my bare hands?

Space: As Red Skull found out firsthand, the Space Stone can send you anywhere in the universe. If you are not precise in your intentions, it will.

Reality: There's a very real risk of becoming trapped in a simulation of your own making as your subconscious feeds the Reality Stone desires. The good news is that it will all collapse as soon as you stop focusing on it, so you'll probably escape eventually. 

Time: Obviously, time travel is dangerous. The worst possibility is essentially hell - trapped in an endless time loop or future sight, dilated relative to "objective" time such that every second which passes in the normal world is a trillion years for you.

Mind: The Mind Stone is less dangerous than most until used in esoteric mechanisms, as happened with Ultron and Vision. For simply holding it, your mental capacity will be expanded to vast limits (and, incidentally, give you the ability to use the other stones in relative safety). The risks of this are in that your enhanced mind may also come with enhanced flaws and that you are now enabled to dangerous things. If you had depression, you now have godlike depression. You'll figure out how to build a planetcracker antimatter bomb in your basement if given a week or two to solve all of physics. There are endless ways for this to end badly for yourself and everyone.

Soul: All of the Stones are intelligent. This is dangerous. But the Soul Stone has an intelligence that expresses regular volition and even opinions. This is dangerous beyond words. To get the Soul Stone you have to have committed a horrifying sacrifice - but that does not mean you are worthy of its power. The Soul Stone may well decide to use your mind as a seat of power instead of the other way around - or if you are more fortunate, it may simply hold open your empathetic gates and let all the suffering of the world flow through you.
