@Alexander M Stanton in my area, IIRC, there can be a maximum of 4 different last names living in a house. So if there's something similar in your area, maybe you can rent the 5 rooms where 2 of them are rented to a pair of brothers or sisters... please check local laws though! Seems like laws around you have a occupancy # limit so that may not work.
Either way that seems like a cramped house, 5 people sharing 2 baths and no living room. Maybe the house layout is alright and I understand it's a younger crowd. Like @Steven Foster Wilson, you will need to consider how utilities, common spaces, common space items are shared. For my house hack rooming situation, I have a roommate agreement along with the lease which gets into those details... I.e. need to keep common areas clean, utilities and common-use items are split evenly among roommates no matter how much/little each person uses, etc. They sign this upfront. It's not perfect but it has worked so far.
