Talaaq

Husband sending text messages to his wife: "Go, I release you" and "I have no claim on you; you can live your own life."

Q: My husband said to me in a text message: "Go, I release you" and "I have no claim on you; you can live your own life." 

Does this count as a valid divorce (talaaq) according to Islamic law? I want to know if these words constitute a clear divorce or not. 

Husband wanting to reconcile after sending divorce notices to his wife

Q: My maid has a situation. Her husband hit her and forced her out of the house two years ago. Then, two months ago, he sent her two divorce notices at the same and one notice saying that she is of bad character and he wants custody of the children. Now, five days ago he sent a third divorce notice. 

He signed the first two notices but didn't sign the third one. He said he did it because he wanted her to feel threatened and come back herself. 

After sending all three notices with the last one sent five days ago, now he wants to get back together. 

Is their Nikah still valid, or are they completely divorced now?

Husband telling his wife "Utalliquki"

Q: Me and my husband were talking about something. I said to him mostly as a joke that I’d like to adopt a child one day from Africa and he got angry thinking that I’m attracted to African men and wanting black kids. This was a misunderstanding but my husband said "I divorce you and you can find another man". He said in Arabic utalliquki which can mean "I divorce you" (now) but my husband said that he meant in the future which counts as warning and not talaq. So I’m scared because this word utalliquki can mean both. 

Is this case treated by the intention of my husband which was to speak about the future "I will" even though he used this word utalliquki.

Husband being forced to sign a talaaq document

Q: My husband's parents forced him to sign a divorce paper. They prepared it by themselves and he doesn't know how many has been written. He didn't have any intention for this. Is it valid? 

They threatened him that his mother will kill herself while his wife put a pistol on her daughter. He did not know how many times divorce was written because he didn't prepare and read the papers, nor was he willing to sign.

Suspending the talaaq

Q: I issued my wife with a verbal talaaq in my fit of anger and my negligence unfortunately. I know that's gone though. 

I then issued 2 suspended talaq as follows: 

1) If she tells anyone in my family or her family about our marital issues and problems then she will be divorced. 

2) If she drives a vehicle she will be divorced. 

Is it possible for me to revoke these suspended talaaqs? 

Is it possible to revoke these suspended talaaqs before the event takes place? 

Is it possible to revoke these suspended talaaqs after the event takes place? 

On another occasion I told my wife the following: "If you not back by 2pm I will divorce you" but I didn't divorce her. It was a threat. Is this counted as a talaaq?

Issuing a talaaq while being forced

Q: My elder brother, recently and was forced to get divorced from his in laws. He was under so much pressure from them, and he was alone at his rented house, and they all forced him to say yes for the divorce. 

But now he is saying that he has not said from his true heart to his wife that I need the divorce from her. So please advise if the divorce is done on his wife or not, because my brother is saying that he has not given her divorce by his heart, but was under pressure from his in laws.
