Nikaah & Marriage Issues

Q: In Islam, is it halaal to get married under 18 but by Law its illegal to get married under 18?

My question is: Can I do nikah but not get married by Law (I'm under 18 and the girl is under 18 too and we are in Europe... In my country like most of the countries its illegal to get married under 18)

Ma Sha Allah im 17 and she is 16 which means we have to wait 2 years... We both are muslims Ma Sha Allah, and she has a "wali" and everything else. Alhamdulilah its okay but that is the one and only problem.

Q: A girl and a boy used to like each other. One day, one of the friends of the boy asks the girl ‘Do you marry Zayd (the boy)?’ The girl replied ‘Yes’ in front of many people. Are they married now?

Q: I am married and a father of one child. My wife is 4-5 weeks pregnant and we both are not ready for this child because my first child was born one month ago with c section and I currently don't have a job and we are in a lot of problems also. Can we opt for an abortion?

Q: I am doing a gcse drama play on lgbt and my role is a Muslim lesbian. Can I do the play or not?

Q: If an Aalimah who wears full niqab and does not intermingle with men or watch tv movies etc. gets a proposal from a doctor whos a hafiz, which means he probably does khalwat with women and he watches football, would you even tell the Aalimah to consider him? He is praised for his akhlaaq. He also visits a female dentist.

Should the Aalimah even consider him. She has hope of doing amr bil maroof but fears marriage problems thereafter. Her grandfather (Allah enlighten his qabr) was a Shaikhul Hadeeth.
