Jamaat Salaah and Imaamat

Q: Can one follow the jamaat salaah of the Haram from the musalla in the hotel/hotel room?

Q: Can one join the saffs on the marble outside the actual Haram, considering the fact that there are huge gaps inbetween the saffs? 

Q: Can a hanafi follow the witr in makkah/madinah?

Q: In a Masjid, a row is usually left empty after every few rows, as it has several pillars.

1. If it is left empty, is the Salah of those behind it valid?

2. Is Salah valid between the pillars?

3. Once, people prayed in that row to the right of a pillar, but to the left of the pillar the row was empty. Was the Salah of those who prayed to the right of the pillar valid?

Q:

1. I wanted to know if two women are reading Taraweeh together, must the one leading for those rakaats stand a little forward and the one following a little behind, or must they stand in line?

2. If one woman isn't reading, can she sit with a Qur'aan next to the one who's reading Taraweeh, and correct her if she makes a mistake ? (The one reading will be reciting in a slightly audible tone, is this permissible as well?)

Q: If one prays in congregation, but due to people praying ahead, he cannot join the saffs ahead, is it permissible:

1. To pray behind an empty space between him and the safs ahead where more than two safs can be formed?

2. OR should he pass in front of musalles to go ahead? What about in the Haram Shareef in Makkah Mukarramah and Masjid Nabwi? Are we allowed to pass in front of musalles?

3. If one prayed behind with an empty space ahead, does the salah need to be repeated?

4. If needs to be repeated, if the prayed salah was janazah, what intention to make for the repeated salah, nafl as janazah salah perhaps cannot be repeated?

Q: If an imaam is a shafi and leads a hanafi community during the year in salaah. What should be done in Ramadan for salaah of witr. If he reads according to shafi mazhab, what happens to those that he is leading who are hanafi? Or should he lead the salaah according the hanafi mazhab?

Q: I caught Maghrib Salaah in the 1st tashahud and on completing salaah I realized that I have completed 4 tashahud in a 3 rakaah salaah. Was this correct? If not, do I need to make Qazaa?

Q: I have been offered by my uncle to perform taraweeh salaah with two cousins of mine at his house. His house is between a musjid and a jamaat khana and is 650m from both. I wanted to find out if we are performing taraweeh there, can we perform the esha salaah there as well or not? 

Q: I would like to know that when should we begin salaah with the imaam, after takbeer in namaz or before namaz. Can a person do itteba of imaam when he makes the niyat?
