Ceiling fans in my grandma's old house

This is a video of the ceiling fans installed in my grandma's house. Wanted to get a video in before they move. The first fan is a new Mainstays from Walmart. Yes, it's missing the motor housing. There's also an older Mainstays white fan. There's also two harbor breeze fans, one is the builder's 42", and the other is a 52" Triton.
