Nikaah & Marriage Issues

Marrying a girl who committed zina

Q: I want to know a fatwa on zina. If a girl do zina once in her life before engagement with someone else and seeks forgiveness from Allah and after sometime she got engaged with a person who did not do zina in his entire life and the girl tells her fiance that she did zina mistakenly. Now she seeks forgiveness since she did this sin. What is the order of shariah about this? Is the nikah halal or haram with that girl?

Hurmat-e-mussaharah

Q: If I touched my mom with lust and hurmat-e-musaahara occurred, now I repented a lot and promise to Allah that I will never do it again.

1. Is my mom still a mahram for me, and do we still have the relationship of "son and mom" ?

2. Do I still have the relationship of "father and son" with my father?

Intimacy with one's spouse

Q: I am married for 6 years and want to have clarity on some topics which will sound disgusting but if I have clear and right information about the same I will carry on forward.

1. In Islam, is it allowed to see, rub, caress, kiss one's wifes anus after cleaning that area and making sure nothing unhygienic is there.

2. Since anal sex is haraam, can I massage/rub with my finger on my wifes anus. I wont be doing any penetration with hand/penis.

3. Can I have sex with my wife in the bathroom and kitchen or any other place in my home.

Marrying one's uncle's daughter after touching her mother with lust

Q: I touched my uncle's wife (mami) with lust when I was 16 or 17 years old. I imagined her while doing a bad thing. I also touched my private part to hers when she was sleeping and kissed her but she didn't noticed. I am very shamefull and regret that.

Now I want to marry my uncle's daughter (mami's daughter). Can I marry her?

Husband marrying wife's aunt (mother's sister)

Q: A girl is 16 years old and she got married to a 27 year old boy knowing that the boy was having an affair with her own aunty (girls mothers real sister). After one month of that girls marriage, her husband got married to her aunty. 

So my question is... is the first marriage halaal or haraam. If it is haraam then can the girl get married to another man without any divorce or khula?

Phone sex

Q: I got married in April and my rukhsati will be in October. During this time period canI talk to my wife on the phone or can we do phone sex?

Can we both masturbate while having phone sex?

Having a simple nikaah

Q: With consent from my parents and siblings, and my husbands entire family (but not his father), I had my Nikkah in November last year. As soon as we announced to my father in law, he was over the moon and incredibly happy. Some realtives also knew about the nikaah beforehand as they arranged our marriage. The Nikaah was beautifully done at the mosque in front of witnesses and my mother and sister. After the Nikaah my parents announced it to other relatives and friends. I and my family received a lot of backlash.

My question is, Islamically did we do any wrong in keeping the nikaah discreet from noise and simplifying it as best as we could? I have received love from my in-laws and family members who were generally happy. Some relatives and family members may forever hold a grudge of some sort. For my own contentment, I wanted to ask if I did anything wrong or were there any mistakes in hiding it from certain family members?
