In Pirates of the Carribean: Dead Men Tells no Tales Jack Sparrow exchanges his compass for drink. As it happens it is told that the compass is betrayed and his greatest fear is released. But before this he gives away the compass many times. He gives it away to Will Turner and Elizabeth Swann also. So why wasn't these actions considered as betraying the compass? Why didn't then his greatest fear was released?

Never forget that most curses and enchantments tend to be omniscient to handwave inconsistencies or the ability to "lie" to a curse.
In the instances you reference, Jack is not giving it away so much as he is loaning it to someone. It remains his compass, and he'll want it back.
But in DMTNT, he sells the compass, therefore giving up ownership over it.
We can argue about details like if renting the compass out would count or not, but the point remains that there is a clear difference in DMTNT whereby Jack intends to transfer ownership of the compass, rather than letting someone else physically carry it.
