Girl living with her parents after nikaah

Q: I have been engaged for over two years now and this December we were going to get married and then he lost his job so he cancelled everything. I want to know if we can make nikaah and I still live at my parents home until he finds a job? I have been very patient in those two years and now I'm tired. I don't mind if he does not take care of me financially, I just feel nikah is the right way I cannot keep on waiting. I explained that he doesn't have to support me until he gets a job and I'm comfortable with it and its not right considering that he comes to visit me all the time.

Husband passing away while the spouses were separated

Q: Me and my husband were living separate and the divorce proceedings were in the court pending . Legally we were not divorced and he never said divorce word to me and while the divorce was pending he passed away his parents and family did not contact me about his passing away and when I said to them he was still my husband because divorce wasn't through yet they said no, in our eyes you are divorced and you have got no right to know he passed away. My question is, was their behaviour right about not letting me know about my husband and telling everyone that they are divorced although divorce wasn't through yet ?

Changing a name that has kufr connotations

Q: We have named my son Keyaan. A friend drew our attention to the origin of his name. The name is from Irish mythology, also belonged to pagan Persian kings, also found that it is widely used in hindu and tamil community. I have checked the Arabic meaning and it means entity. As for any words, entity also has a vast array of meanings. One of the meanings is ghost or spirit or anything that is living or non living, anything from the unseen. So far I don't see anything positive about the name. Please clarify and let me know whether my findings are correct.
