Witr and Nawaafil

Q: I have a friend who is around 15 and 16 years old and is a Hafiz of the Quran. He is willing to lead taraweeh this year but he is not sure if he is baaligh. What should he do?

Q:

1. What is the difference between ishraaq, chaasht and awaabeen salaah? Some people say that they are all one nafil salaah, but the names and times are different. Why are these separately described in the ahaadeeth?

2. If someone read ishraaq, does he need to read chaasht as well?

Q:

1. If Asr salaah is prayed in a makrooh time, can the four rakaat sunnah be prayed before the fardh?

2. The makrooh time, I understand starts 20 minutes before Maghrib. Is it right?

Q: Is sleeping after tahajjud permissible?

Q: I heard that one should not pray two times witr in one night. I forgot whether I prayed witr or not after isha. What to do? 

Q: I want to ask if one can perform 2 rakat nafl namaz of istikhara for multiple purposes. Like, if I want to marry a girl and want to know if she is good for me or not and at the same time I want to know if a job is good for me or not which I have applied for. If yes, how can one determine which (dream or inclination) is for which purpose?

Q: What is the procedure to be followed:

1. If we missed the 2 Rakat sunnat of Fajr?

2. If we missed the 4 Rakat sunnat of Zohar prayer before Farz?

3. What is the sequence to be followed for Sunnats after Juma prayer (2 Rakat first and then 4 rakat or the opposite of it?)

Q: In our locality in the middle east, all local people pray Tahiyyatul Masjid between azan and Maghrib and those who don’t pray are sometimes instructed to pray and not to sit without praying; but on the other hand, there are people from India and Pakistan who say if you will pray, our children will get confused and think it is ok to pray at this time. What should we do in this situation? Pray or go in the Masjid and sit waiting for Maghrib prayer?

Q: Is it permissible to sit and pray nafl salah even if one is physically fit. I see lot of people who are doing hard physically challenging work but when it comes to prayer, they sit and offer the sunnah prayers in dhuhur maghrib and eesha.

Q: Can I perform salatul tasbeeh namaz in 2-2 rakaats?
