What do you mean explain more... already father name is in passport and Lebanese identity card..

I mean can I add a second name on my identity card?
In fact I have 2 names some people call me in my first name and other people call me in my second name. But on my identity card it is written only one name. can I add the second name on the identity card?

Dear Hamid, Yes that way it is feasible. It can be Your Name Known by This Name. That way is ok... but you have to convince the tribunal.

thank you for your answer

can i change my name just because I want to change it?

The case of changing a name is not easy to win, you have to convince the judge by presenting serious reason... my name is old fashion or am bored of it is not a serious reason...
