While in Turkey I´ve noticed that friends sometimes talk to each other using ending that sounds like ´be´ egzample Recepebe,Hasanbe etc.What does it mean?

its bey and I think it means mr

So...all men are "bey´´ but no woman is ´´hanım´´ 

There isn´T such a suffix "-be" that I am aware of; It can be one of these two:

(Edit:  I seem to have forgotten bey, I realized after reading some other posts, yes bey is probably the most likely, it simply means mr)

"abi" = It means big brother. Friends also call each other abi. So it can be Hasan abi etc. maybe. (People refer to their friends as baba(father), hocam(my Hodga), hacı(hadji, pilgrim), müdür(executive?), usta(craftsman) etc. in slang usage.. Don´t get confused these do not retain their meanings as in the case with abi)

"be" = This is just some sort of exclamation like hey, yo, oi etc.. You can hear this even in some other Balkan countries.

hadi be , yürü be

 bayan

 Deli Hanım

No; hanım is as common as bey. When referring to people with their names, you should use hanım or bey if you are not personally close with them.

A side note here: My etymology dcitionary shows that hanım, actually derives from "my han", probably referring to rulers wife. (Han = Khan, e.g. Genghis Khan). Interesting

hanfendi (hanım efendi)

the most polite version i think.

 Well, although they had different derivations, the current usage tends to be for a polite title:

For a Turk: Put Bey or Hanım after the name

For a foreigner: Put Bay or Bayan before the name

e.g. Recep Bey

Ayşe Hanım

Bay William

Bayan Margaret

If they call you William Bey or Marion Hanım, you know you have crossed the foreigner/Turk divide!
