Want to add a friend system? Use the following commands/ functions:

/scoreboard players operation @p[tag=acceptFriend] locationID1 = @p[tag=addingFriend] locationID
This sets locationID1's value for the person with the tag acceptFriend equal to the person with the tag addingFriend. 
/function locationDB1 
This will teleport the person to their 1st friends island. 

You can do the same for /function locationDB2 and /function locationDB3 to add up to three friends. 

Enjoy
