Bismillah, 

Asalamu Alaykom, 

Firstly I pray that you may come out of the current situation you are in and that you may be blessed with the best of houses.
 

The example you have mentioned would not permit one to shorten their Salahs and doing so would make your Salah incomplete. You should try your best to make sure that you are praying each Salah in full unless you are able to shorten with the correct conditions.
 

These salahs would not be valid as they are incomplete. in terms of combining if you mean praying Asr after zuhr, and isha after Maghreb, then this is always valid regardless of where one is. 
 

May Allah grant you success
