Dual boot windows 11 with mac os

Hello, i have nearly no knowledge in this area but i would like to ask if this is actually like a good idea to install to operating systems on the same hardrive

how much storage does it usually take?

does the idle/not working at the moment os use ram or not?

Can i install the mac os on a external hardrive?

Is it better to just install mac alone on a laptop?

Specs: 16 gb ram (thinking of upgrading to 32gb) 500gb ssd and 5tb ssd external Ryzen 7 5600H

Thank you.
