Will touching a dry impurity make one impure?

Q: I am currently abroad and I have been doubting everything recently. I was recently told that theres a potential of lard (pig fat) being used in the making of bread here in some of the bakeries. My friends eat that bread because they are non Muslims.

My question is, if they were to eat the bread which is a dry entity and then touch me with it after they are done, would I become najis, or does impurity only travel through wetness?

Inheritance

Q: My father died 3 years ago and he left some property behind and he didn’t write any will. He has only five daughters and a wife. His father and mother are not alive and he has no siblings from father's side but his mother got married to another man and she has 4 children. All his property is self made and he didn’t get a penny from his mother or anyone. Do we need to give some share to his brothers and sisters from his maternal side?

Reuniting after khula'

Q: My wife got a separation from me through court and that is khula. No divorce word is mentioned. I did not take mahar amount from her. She also took my 3 million rupees and did not give me back at that time and not yet even. I love her and we have 2 daughters. Khula is done on 8th January 2018. I am giving her all amount of her expenses also. After two months we had intercourse with an intention to live together again and I promised her that nothing will go wrong by the grace of Allah. Is her khula valid after all this? What do I do to bring her back?
