I understand how to call a function for every member of a group, like in the Docs:
get_tree().call_group(0, "guards", "player_was_discovered")
But is it posible that I can add a variable to the function, like by a normal function, for example:
func player_was_discoverd(variable):
pass

Yes, just append the variables you want to pass in the end:
get_tree().call_group("guards", "player_was_discovered", 3, "Hohoho, got ya again!")
You can then use them like any normal arugment:
func player_was_discovered(times_catched, taunt):
print("You have been discovered by guard number %d. He yells: %s" % [times_catched, taunt])
I tried it and it works with one or two variables, but if I have three or more variables it doesnt work any more. Is it necessary to change something, if I use three variables or can I only use one or two variables?

If you’re passing more arguments to the function like here:
get_tree().call_group("guards", "player_was_discovered", 1, 2, 3, 4)
you also have to adapt the function of course:
func player_was_discovered(arg1, arg2, arg3, arg4):
print("%d %d %d %d" % [arg1, arg2, arg3, arg4])
You also can pass an array of arguments:
get_tree().call_group("guards", "player_was_discovered", [1, 2, 3, 4])
Then you can have a generic callback:
func player_was_discovered(args):
print("%d %d %d %d" % args)
