Masbooq and Laahiq

Q: If I miss one or two rakats of jamaat salaah, will I get the reward of jamaat salaah? Till what stage of salaah if one joins will he get the reward of jamaat? 

Q: I have a few questions regarding a late comer joining salaah:

1.Is it important to recite sana once you standup to complete your prayer?

2. What if sana was recited when the person joined in the 2nd, 3rd or 4th rakaat

3. Due to misunderstanding and following someone, if a person follows a different procedure to complete the missed rakaats in salaah for a couple of years and now he comes to know correct Hanafi procedure, will his passed salaahs be valid?

4. Is the below procedure correct as per Hanafi mazhab: If a person joins jamaat salaah and says salaam at the end of the 2nd rakaat and after salam he stands up and doesnt read sana and treats this rakat as the 4th rakaat. He only recites surah fatiha and completes his salah. Is his salaah valid or does he have to stand up recite sana, surah fatiha and a surah to complete his salah?

Q: If I joined the maghrib salaah in the last rakaat or while the imaam was reciting tashahhud of the second rakaat, then how should I perform the two rakaats that I missed, and when should I recite the thana?

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:

1. In Witr Salaah in the month of Ramadhan, if the masbooq joins the Imam in the ruku of the last rakat, is it wajib for the masbooq to recite dua e qunoot when he stands up to complete his missed rakat and in which rakat will he recite dua e qunoot?

2. In Witr Salaah, if the masbooq missed all the rakaats and did not recite dua e qunoot when he stood up to complete his Salaah, is it compulsory upon him to repeat the Witr Salaah after the Salaah time has expired?

3a. If the masbooq turned for salaam with the Imam accidentally or not knowing the masala and he did sajdah sahw at the end, is the Salaah valid?

3b. In the above situation, if he didn't do sajdah sahw, is it compulsory to repeat the Salaah when the Salaah time has expired or is the Salaah valid but incomplete?

4a. When the Imam did salaam to do sajdah sahw, the masbooq accidentally or not knowing the masala, he also turned his head for salaam and then did sajdah sahw at the end of the Salaah, is the Salaah valid?

4b. In the above situation, if he didn't do sajdah sahw, is it compulsory to repeat the Salaah when the Salaah time has expired or is the Salaah valid but incomplete?

Q:

1. Suppose I am offering Asar or Maghrib and I joined the Namaz in the last Rakaat after missing the first three rakats, now when the prayer ends with "Assalaamu alaikum warahmatullah" by Imam and I get up from "Attahiyyaat", Then what do I have to say first? Do I have to start my next rakat with thana or bismillah?

2. Also, do I have to say a surat after reciting surah fatiha?

Q: I was praying Asr Salaah with Jamaat and had missed 3 rakats. I forgot to recite a surah in the second rakah, so I recited a surah in the third rakah, and also did sajdah sahw. Is this correct?

Q: Can you please tell me the method for how to join jamaat salaah if I am late?
