Just to put Saucy right, sorry you may have already spotted your mistake, Saruman was a Maia, not a Vala. Also the Noldor lived in Aman with the Powers, learning much of Aule.

The Wizards Pallando and Alatar are linked to Orome in UF, so if we look at the description of this Vala, we read:

Orome loved the lands of Middle-earth, and left them unwillingly and came last to Valinor; and often of old he passed back east over the mountains and returned with his host to the hills and the plains. He is a hunter of monsters and fell beasts, and he delights in horses and hounds; and all trees he loves, for which reason he is called Aldaron, and by the Sindar Tauron, the Lord of Forests.

Orome also trained his folk in the pursuit of the evil creatures of Melkor.

So here are a few possible reasons why at least three of the five went east:

1. To give aid to any of the remaining good Children of Iluvatar.

2. To protect any forests, that may still have Ents/Entwives living there.

3. To pursue any remaining creatures of Melkor ie: A Balrog/Dragon.

4. To stop the Men of the East from serving Sauron.
