Talaaq situation

Q: My husband gave me a talaaq a few years ago. He sent me to live in Pakistan and gave me a conditional talaaq notice of 2 remaining talaaqs via email that if I come back to UK to him they will become valid. Is there any way I can go back to UK but still the talaaqs will not be valid or if they become valid if I go back to UK without his permission, do I need to do something about it while I stay back in Pakistan? Please help in the light of your knowledge.

Revoking the talaaq after the second divorce

Q: I follow the hanafi madhab. I divorced my wife one time and then I went back to her by just uttering the words I take you back as my wife then I divorced her a second time after a few days and then I went back to her by just uttering words I take you back and accept you as my wife. Recently a friend of mine told me that I can't do that. After the second time I must have an imam and witnesses and marry her again the way I first married her. I am worried now. I have already divorced her for the third time now but I am concerned that when I became intimate with her after the second divorce did I fall in sin?

The name Feroz and Feroza

Q: What does a boys name Feroz and girls name Feroza mean? I was told it's not permissible to keep a girls name Feroza and boys name Feroz,is this true? If yes will it be compulsory to change the name if the above names were kept and is it a sin if the names are not changed?
