the second sounds like gremlins

Heavy Metal is the only movie that comes to mind?

The 2nd one sounds like the serpent and the rainbow from what i remember ,but i think its alot older than that

Was it Hell Night?

No not really i wish i could

I think a girl gets murdered and a guy is found dead stuffed in a refrigerator wearing a costume with a cape ,like a superman suit i don't remember if he was hiding and suffocated or if he was killed...
