A dubious guess for #14: is he HALF FAST (ie, still, steady), = HALFAST?
15: I was assuming Hola, but it seems VALE is a Spanish greeting too. Balin's dad is Fundin, and if we remove F for forward (or indeed formen) we can get... pretty close to VALE OF ANDUIN. Which isn't too far from Moria, and in fact is right next to where Balin lies down in Beorn's house.
