Yusuf sees Havva and Küçük Yılmaz in the hotel; apparently he has been deceived. Seeing the love of his life in the arms of another (man) confounds him. Havva is very happy, because she took revenge on Yusuf. However, Küçük Yılmaz is not aware of the fact that he is starting not to be her lover. Talking to Sultan Reşit, Şeref and Remzi Küçük accidentally find out the thruth about Yılmaz. Şeref is shocked and Sultan is puzzled and dumbfounded. Bade fails everytime he tries to escape from Mehmet. Mehmet says that the baby knows [she/he/it] is from him. Bade denies, but the truth is in the middle. Havva tells Şeref that she and Küçük Yılmaz loved each other. However, Şeref is very angry, his forgiveness won’t come easy. Yusuf decides to come back to the residence; Bade received another blow. Either he will lose this war or he will accept living under the same roof with Havva. As the cold war in the residence continues, Havva’s whole world is again close to be upside down.
I´m still a learner, so you can´t be sure my translation is 100% correct.
I marked the phrases I had problems with in red:
*Sultan ise ne yapacağını bilemez halde kalakalır
Literally it says: "Sultan is petrified in a state which can´t know what to do"
*gerçek ortadadır artık
"the truth is in the middle ever after" ? something like this...
But I don´t know why the word "artık" is placed after the verb. It´s like an inverted order.
*yine alt üst olmak üzeredir
"is again close to be upside down", that´s only my suggestion, I´m not sure.
Please any native speaker review my translation and explain to me the use of the phrases I had problems with 
Sufler, I like reviewing tranlations but if you could translate sentences one by one and write your translations under the orginal sentences with a different font, it would be easier for me to control them.
1)Your translation is correct. Kalakalmak means "not to be able to do something", "to be shocked"
3)Your translation is correct. Alt üst olmak means "to be very upset" if you use it for a person. Ex: Ayşe altüst oldu.
