I would like to know that sometimes when we get home late after work we don’t get time for namaz at work and we have to read it when we come back home. Now since it’s winters in USA and Maghrib is around 5:20. Is it okay to do zuhur and asr salaat as soon as we get home before maghrib? Also, since it’s almost maghrib time can we pray maghrib in the same wudhu or do we have to do wuzu again for maghrib??

First of all it is not allowed to make the namaz qadha.. You must get a place to pray during the time.

However if the time of Maghrib has come then you must pray Maghrib first and then pray any namaz that has become qadha.

You can pray all the namaz with one wudhu as long as it is valid.
