I posted this question and now i'm going to answer it.Firmware that i installed manually was Lollipop.Previously i upgraded to Marshmallow by Software update option in mobile.Now recently i again installed Marshmallow firmware but this time i did it manually,i downloaded firmware from Sammobile. Finally, issue is solved now in new Marshmallow.Now Skype is working fine and that problem(the problem was that i was not able to change my security lock screen password) about Marshmallow is also removed.Thanks to Sammobile web site.
