I suggest slenderman or five nights at freddys. Two pretty fun an "scary games"

I would suggest outlast, I think it`s a great game!

Slender: The Arrival was a pretty good horror game, they added a bunch to that game that really makes you not want to go to certain areas because you know what's going to be there, yet, if you don't, you either don't progress or your die because you're standing around. Outlast was also a decent game, pretty much the same, you're armed with a camera that is used as your flashlight and night vision, you wander around, trying to not be killed by everything in the mansion. I haven't played Amnesia but it used to have a hype behind it, not sure why, but you can check that out too if you want.

Out of the games that you list, I've played Alien Isolation and thoroughly enjoyed. It can also be quite scary and intense during some parts. So that would be a good game to pick up. I haven't played the other two yet, but I'm thinking that I'm going to pick up The Evil Within this week after I get paid. So I'll be able to tell you how it is in a couple of days.

A few other people mentioned Amnesia. It is an alright game, and it does have a few scary parts. But overall there are better horror games out there. I've heard that Outlast is really scary, but haven't played it yet. But it could also be a good game to try.

You should play the original Resident Evils they still hold up pretty well.

Cry of Fear looks fun and scary. Worth the try
