By the time you walk the five minutes from the bus arrivals gate to the bus departures gate, they should have just started boarding. And they almost always send two buses, so even if you're on the second bus, it shouldn't be a problem. Assuming you're able to do online check-in for the return.
I wouldn't be so sure. It is not unusual to start bus boarding as the plane is merely arriving (even if it means keeping people in the bus for a while) to try and catch up on delay. It's happened to me multiple times for bus boarding to start minutes after I've seen my plane landing late. As for cleaning during the rotation, we all know what a relative concept that is so I'd certainly wouldn't count on that to keep the plane on the ground long enough.
