Horror Fiction Help XVIII

These sound familiar to anyone? 

1. From probably 1960s and certainly not newer than 1972ish. The cover art had a pair of women's (I think) shoes and the shoes had scary, moaning faces.

2. Something to do with a nightmare and a haunting. It has three golden monsters on from '91 and it looks like a apple paper back or an Avon but it's not. I think a character's name is little Jack.

3. I thought it was called "Little Angel" or a variant thereof. I remember the cover was an illustration of an innocent-looking little boy, around 10 years old, sitting next to a broken birdcage with feathers and blood all over the place. And he's got this "Who, me?" expression on his face. It was a rip-off of "The Bad Seed," and concerned an evil little psychopath boy, around 10 years old or so, who lived with his parents. His mom spoiled him rotten, but his dad suspected that he might be evil. Of course, nobody believed him. I remember the little boy tries to kill his aunt at one point by throwing her off a cliff, but she's hanging on for dear life and somehow manages to attach herself to the side of the cliff with her belt. And the little boy is bitching that she spanked him for wetting his pants when he was younger, and how much he wants her to die. She survives, but her arm is all bruised and dislocated from hanging onto the cliff for so long. Then his teacher ends up with a broken arm because he bum-rushes her on the playground and knocks her onto a pile of gravel. The dad tries to talk to her about the incident, and ask if she suspects his son, but she thinks the boy is innocent and he's crazy. The dad and the aunt team up to stop the boy, much to the mom's chagrin. But then the mom somehow gets on the boy's bad side and he tries to kill her, too. But the dad somehow stops him, and I think he accidentally kills the boy. At the end, the mom lays dying in the hospital and gives her blessing for the dad to marry the aunt, because she knew all along that they were more well-suited for each other. I used to love reading this trashy pulp novel, but I lost it a long time ago, and I'd love to figure out what it was called, and maybe read it again. Found! It's: 

 
4. The book is set in a psychiatric hospital for the criminally insane in a very cold region of America where a new doctor is trying a new form of treatment for a particular patient. This patient was guilty of a series of murders of women where he strung them up and basically bled them dry, possibly showering in their blood. He is heavily medicated but the doctor thinks that he can "get through" to him by cutting his medication. The book basically goes through flashbacks showing how the killer developed into what he is and introduces characters and sets up future confrontations between staff and patients. In the end the patients revolt and escape setting up a chase between the main good characters and the main bad characters in a violent snowstorm. As I mentioned, I cannot remember the name of the book but it may have had "Snow" or "Winter"in the title, but I can't say for sure. Found! It's that perennial used paperback I see in virtually every used bookstore I visit but have never read:

5. I read a book in which the one of the main characters in this short story collection, I believe i remember this correctly, fell in love with a sheep. There was another story that involved necrophilia. There was nothing graphic or gross. Instead, it was this amazing depiction of loneliness. I think it took place in big sky country, maybe Nebraska.  Found! It's:
