Can I take the food she has in my fridge out so I can put my food in there? Can I take my stuff out of my house, like my couches if I want to if that's where she sleeps
Yes, and yes. Although if she wanted to make an issue of it she could hold you responsible for the value of the food. It is likely a petty amount not worth worrying about.
Before removing it, maybe give her one last chance to remove it herself.
She has no right to your couch. You can sell it, send it out to be reupholstered, or simply put it in storage. It's none of her business.
