Takbeer-e-tahreemah and Qiyaam

Q: Can we recite sana when joining the Salah while the imaam is reciting a Surah? 

Q:

1. When starting salah, do your hands have to be facing qiblah?

2. Will salah be valid if you start salah with your hands facing inward towards your head? One time my imam for salatul jumuah started salah and I think his hands were facing inward. What should I do in such a situation if my jumuah is invalid and I am going to have to wait for second jumuah or go catch jumuah at another masjid?

Q: Is it permissible in Hanafi madhab to do rafa' yadhain? Please clarify.

Q: I heard that that the hands should be placed on the chest during salah because there are sahih hadith on this. And also, the hadith of placing hands below the navel is weak. Is this true? I've been told it doesn't matter much where the hands are placed as long as the prayers are offered, but I still would like to know the correct way.

Q: Can I pray my fardh namaaz without saying takbeer-e-ula when I am praying my namaaz just myself?

Q: When the Imaam ends the qiraat before going to ruku, some people drop their hands before the Imaam says the takbir. What is the Shar'ee ruling regarding this? Is it permissible for them to drop their hands?

Q: I want to know what is takbeer-e-ula?

Q: What is the ruling with regards to touching the earlobes while saying takbeer-e-tahreema? I was told it is makrooh. Can mufti saheb please indicate as to where this masala can be found?

Q: I just want to ask when praying where should I place my hands? Is it below or above the navel? I follow Imam Abu Hanifa. Jazakallahu khayr.

Q: Could Mufti Saab please advise me on how one should continue after reciting a dua in the middle of a Surah.
