Your girls sound normal to me!
My little Gary (5 mnths) loves to play with Willow (3 mnths) , a foster kitten, especially at night. This is usually doing laps of the house, thundering up and down the stairs like elephants at 4 am! Then they play "kill" each other, and Lily goes to sort those two boys out, so it goes on!
I shut Willow downstairs, away from Gary to keep the calm. If Gary and Lily start, then they get shut out of the bedroom. That is reserved for oldies Freddie and Colin who need their beauty sleep and can be relied on to behave.
I have to get up early due to work, chickens wanting to get up, numerous reasons. Willow and Gary can play all they like after 6am!
