I’m unsure how to install crown molding in these wacky areas in a way that would look professional.

I’m open to any suggestions here. I’ve been learning a lot after buying this fixer upper. The biggest thing I’ve learned is to slow down and not waste time/money doing something like a noob. It’s been hard since this whole house was built by a (at the time) noob, and now I’m trying to make it all look right. I have no idea how to continue my crown molding on these sections.
