Making a second Jamaat

Q: When we are in Saudi, in some masjids they perform a second congregation. Are we allowed to take part in that congregation if we haven't already read our salaah?

Q: As you are aware, in Gulf countries, in the Masjid after the main congregation is over, there are many second and third small congregation/jamaat prayers going on in the masjid with 5 people or 6 people or 10 people ,and so forth. As far as I know, in Hanafi Fiqh, it is not considered okay to make second jamaat in the masjid. As a Hanafi, what should a tourist visiting a Gulf country or a resident of a Gulf country do if he misses the main congregation and he sees the second smaller congregations of a handful people going on? Should he join it or should he pray the fardh separately?

Q: Is it permissible to have 2 jamaats in the masjid for the same prayer?

Q: In some masjids, there is a seperate entrance, like a connecting room, before the main praying hall, where people keep their shoes. The doors of the masjid first open into this entrance, and then there is another door to the main praying hall where the imam leads the salaah. Often this area is carpetted for praying. Is it allowed to make a second congregation (jamaat) in this entrance?

Q: There is a masjid inside a university where many Muslim students live, but it often does not have any jamaat salaah on Sundays, though the Friday prayer is held there.

An imam is appointed for the masjid, but he often does not come for Fajr, Isha and prayers on weekends (maybe because he lives far from the university). When the imam is not present, anyone leads the prayer. Is it correct to start a 2nd jamaat after the imam has already led the 1st jamaat salaah?

Q:

1. There is a masjid inside a university where many Muslim students live, but it often does not have any jamaat on Sundays, though Friday prayer is held there. An imam is appointed for the masjid, but he often does not come for fajr, isha and prayers on weekends (maybe because he lives far from the university). Is it correct to start a 2nd jamaat after the imam has already led the 1st jamaat in Salaah?

2. Is it correct to offer Friday prayer in this mosque?

3. I led a 2nd jamaat in this masjid, but after I started, I heard someone else leading another jamaat in the corner of the masjid. I did not know this before I started. Will I and my muqtadi's have to repeat the Salaah?

Q: If due to rain in certain parts of the world, Maghrib and Isha’ are prayed together in the masjid. Would it be permissible for Hanafis to conduct a second congregational Isha’ prayer in that masjid, because it is forbidden to conduct second congregation prayer in a masjid?

Q: If some people enter a Musjid after the first jamaat is over, is it permissible for them to make a second jamaat in the sehn of the Musjid or should they perform their Salaah individually in the Musjid or the sehn of the Musjid?

Q: If a group of people, who are not musaafirs, come late to the musjid after the first Jamaat is over, will it be better for each person to perform his Salaah individually or for them to make a second jamaat? Will the same ruling apply if they perform their Salaah in the sehn of the musjid? (i.e. will it be better for each person to perform his Salaah individually or for them to make a second jamaat in the sehn?)

Q: A school in our locality performs Zohar Salaah in the Musjid before the Musjid actual time. The Musjid time is 13:15 The Schools performs salaah at 12:45. Is this permissible? The school is situated next to the Musjid.
