Iyi gunler, nasilsin iyimisin Mansurla gorustunmu? Mansur izin icin onay almis 5 eylul´den itibaren izne gelecek sende islerini ona gore ayarla hayirli olsun seni bekliyoruz. Burada havalar sick biz hepimiz iyiyiz. Ailen nasilsin annene ve abine selam soyle annemin tum ailene selami var. sen ne zaman geleceksin bildirimisin. Guzel gunler dilerim. "

Think it is asking about my family, giving them greetings. telling me that Mansur has leave on 5 Sept and asking if I have spoken to him. Also about the weather being good. Would be good to have this confirmed.

Many thanks.

You have translated this as well as I can and  I basically concur.    In first line  after "good day, how are you) it seems they ask if your meeting (talking) with Mansur was good.  Seems casual and Ok.  (DId you see him?)  Or possibly they ask if he is well.  (more probable).   I see no problems. You should proceed with your understanding.
