I think only (1) is correct.
(2) would mean that the _expression_ "Alice's Friend" is synonymous with "Bob", or something like that.
Also, according to my understanding, $is is commutative and transitive, i.e. if you had this:
=alice+friend/$is/=bob
=alice+friend/$is/=charlie
Then you could infer =bob/$is/=charlie, which I think is not the intention..

Lastly, a question.
What is the semantic difference, if any, between the two statement sets below?
(1) =alice +friend =bob
(2a) =alice () +friend
(2b) =alice+friend $is =bob
