Equality between wives

Q: If one's husband has made nikaah without telling her and she found out about 3 months later. Her husband did not consummate the marriage and after consulting with his seniors, he regrets what he had done. However he is afraid to divorce the second wife due to backlash. The first wife wants to make dua that he leaves his second wife since he hasn't caused her to to become pregnant which will further complicate things. 

My question is, is one allowed to make a dua as such... "Oh my beloved Allah you create a good excuse for my husband to leave his second nikaah with aafiyah and you make it such that she finds a better spouse for her thereafter". 

Will this kind of dua be allowed?

Q: Should there be a reason to take more than 1 wife, or a condition to marry a second wife?

Q: I am a second wife and my husband hasn't lived with me since the day of our walimah. It's been almost a year that we've been married and my husband only comes to me for 2-3 hours a day. In this year, I was also pregnant but the timing of my husband remained the same. Now I want him to stay with me the exact amount of time he didn't spend with me in the last year. 

Q: I have taken a second wife - but before I had married her we had an agreement in place that I will not stay every second night with her. Now she is demanding that right. She is a revert. She said that she didn’t know how hard it was going to be a second wife. She knew from the beginning the Islamic laws of 2nd wife.

Is she valid in her argument and can she change her mind and do I have to now fulfill her right?

Q: If I marry a second wife while I am in financial difficulty? Can I treat each wife according to my financial capacity? I will request both of them to accept my financial position. Can I marry a second wife with her consent of supporting her with only a monthly budget of 20000 rupees.

Q: Presently I have two wives. I married with my first wife while I was studying in Turkey and she got official status of my wife in the online government system in Turkey. I have married again a couple months back. Now I got a job in Turkey, where I can take my first wife only (since she is registered there and two wives are not allowed in Turkey) and cannot take my second wife due to the given reason. I am confused as to what to do?

If I take my first wife only and visit Pakistan in the holidays or call her on a tourist visa off and on, will this be fine and justified? Please advise me as to what I should do so that I may not become sinful?

Q: In kitchen where co-wives work together, occasionally the husband places hands on buttocks or breasts of one wife in front of another. The two wives have no qualms about it. But is it permissible in Islam?

Q: How do you share food for your wives when one's children are more than the others. For example, if the first wife has 4 children and the second wife has 8 children and the third has 6 children; is sharing the same quantity for them justice?
