Touching a cloth with dry napaak hands

Q: I have read that in order for najasat to transfer from one place to another, flowing wetness needs to be transferred. Now if my hands are not paak but dry, and I hold a cloth in my hand, does it become napaak?? The point where I am confused is that a hand is always sweating and in bright light very tiny droplets of sweat are always visible. Now if in such a scenario, if I touch a cloth, given my hands are not paak but apparently dry and I cannot see any wetness transferred to the cloth, does the cloth remain paak? Does this situation correlate with the ruling that a najsat with size less than a dirham coin could be ignored?

Inheritance

Q: My question is about inheritance according to Islamic Shari'a law. I have a stepmother who has no kids, I have one brother and one sister. What would be the inheritance share from a deceased man in case of two sons, one daughter and wife (our step mother) who has no kids. Our mother died long time ago.

Washing dried semen

Q: I had released semen at night which had dried on my private area when I woke up in morning. When I did ghusl, the dried semen was not coming out, even after scratching or rubbing the skin. I left it and completed my ghusl, and offered fajr. This dried semen did not come out until I scratched it again after a week, and even then I think it did not come out completely.

1. Does this dried semen keep me impure?

2. Will I have to repeat the prayers I offered with this?

Discussing one's sins with others

Q: I understand that it is a sin to discuss one's sin with a friend due to it showing a lack of shame. What if I am the one who hasn't committed the sin, but it's my friend that is talking about matters that relates to his sins with me? How should I handle these conversations despite already trying to give da'wah? Do I get sins also for indulging or contributing to this conversation since it might be displeasing to Allah? 

Method of making salaam in salaah

Q: What is the correct way of tasleem in namaz. What I know is, at the end of salah, should I start saying salam (assalamu alaikum wa rahmatullah) when my head is towards the qibla and continue saying salam while I turn my head towards the right and complete saying salam after I complete turning my head. This completes the first salam. Should I turn my head towards the qibla then I should start saying salam when my head is towards the qibla and continue saying salam while I turn my head towards the left and completes saying salam after I complete turning my head. This completes the second salam.

I have observed the following three cases in case of three imams who are leading prayers. Could you please clarify if the salah is valid in these cases.

1. At the end of salah,the imam turns his head towards the right and after completely turning he says salam. Then he turns his head to the left after completely turning he says second salam. Is salah valid in this case? Why I am asking this question is , I have read somewhere (I guess it is from a shia person) that if you turn your head during salah your salah will become invalid. In this case the imam first turned his head to the right, by the time he starts saying the salam his salah has already become invalid.

2. The imam completes the first salam properly as per my understanding. But he starts saying the second salam when his head is turned towards the right and continue saying the salam while he turns his head towards the left and completes saying the salam after he completes turning his head towards the left. Is salah valid in this case?

3. At the end of salah, the imam completes saying salam when his head is towards the qibla then he turns his head towards the right. Then he turns his head towards the qibla and completes saying salam when his head is towards the qibla then he turns his head towards the left. Is salah valid in this case?
