OK, the strategy IMO should be to go for the stars missing in the Milestone tracker on top.
To get the 5th be in your own bathroom at 14.00 and skip time. Emily should show up.
To get the 6th you need to advance in Chloe's pet training, but I can't see from the screenshot where you are in this event.
All the right hand missing stars are just a matter of peeking / entering. Use F5/F8 to get the desired result without too much grind (peeking in Rachel's room and stay until the end without being caught), peeking entering the common bathroom and Emily's room (this one is the morning).
Aunt makes mistake : peek without being caught when Rachel is with Susan.
Is she sick : peek / enter Chloe's room early in the morning.
I see to particular difficulty to progress from where you are. If there is one event blocking you, just post here your progress status and the thing that you can't get to happen.
