Times of Salaah

Q: Is it permissible for a hanafi to follow a shafi jamaat for asr salaah if the time for asr hasnt set in for hanafi yet? What is the ruling and other important points to note?

Q: When we go for umrah, all the umrah busses stop for asr prayer according to shafiee time. We (ladies) strictly follow hanafi time. In winters, due to school, we read our zuhur salah after the shafiee asr azan, as hanafi zuhur salaah time is still there. We also read our asr according to hanafi time i.e. late.

So my question is... the bus stops for asr at shafiee time. If we do not get the jamaat, what should we do? Can we read at shafiee time at such circumstances? 

Q: If a person starts his Asr salaah just before sunset and the time of sunset enters whilst he is performing it, is the salaah accepted?

Q: I am currently excused (chronic excuse) with regards to wudu due to bleeding. I know that my wudu breaks when the next prayer time comes in. However once or twice I took too long to pray and when I checked the time, I was a few minutes into the next prayer time. Are those prayers invalid? Would they be invalid if I wasn't excused with regards to wudu?

Q: I want to know when can we offer Maghrib prayer if we miss it while traveling back to home from the office? Can we offer it with Esha prayer??

Q: I want to know qaza times for all 5 times salaah. What is the duration of time for qaza for each salaah?

Q: I want to know what should I do if I miss a prayer in traveling? For example, the Zuher prayer is offered from 1 t 2 PM but when I reach home its already 4 PM. So what should I do in such a situation? Should I perform the complete Zuher prayer at 4 PM or only offer the farz (obligatory prayer)? 

Q: What's the ruling on joining two salaahs as a musafir?

Q: If I am traveling from safar and I am on my way home, what is the latest time I can read magrib namaaz?
