in PC notebook you have left and right function key, how can I use the right key on Macbook which has only one?

Hold control while clicking.

OTOH you can use a two finger tap to emulate the right click.
Sys Prefs > Keyboard and Mouse > Trackpad > Tap trackpad using two fingers for secondary click

There's also an option to click the button while two fingers touch the trackpad (for those of us not used to the tapping thing).
