I'm assuming you mean the hosts file. That's kinda like an override... The "when you type this, I want you to go here" file. It's not the same, but serves a related purpose.

Most older routers (stock firmware) would let you redirect from your ISP's DNS servers to one of your choice, Custom firmware did allow you. If memory servers, there were some routers which would not let you, but that was a long time ago. Static routing is not the same thing.
Static routing has a specific purpose.

You mean as primary/secondary DNS? Yes, they should. There are tests out there you can use to confirm that.
