Casual Person

Chosen answer: We are never told, but given his confidence in his rabbits and the fact that he is a wizard of equal power to Gandalf (even if he has gone a bit odd), we can presume he escapes. Radagast doesn't appear in the book, his presence was pretty much invented for the movie, however he does appear very briefly in the first book of the Lord of the Rings (though not in the movie), so as far as the overall story goes, he must survive.

Chosen answer: It took Gollum a few years to summon up the courage to leave his cave to try to find Bilbo, but, unsurprisingly, he found that the trail had gone cold. Wandering in the hope of picking up the scent, he ended up on the edge of Mordor, where he encountered Shelob and became her servant, spying on her behalf, luring food into her lair and so forth. Eventually, captured by Sauron's forces, he gave up the names of Baggins and the Shire under torture, alerting Sauron to the existence and potential significance of Hobbits. He was freed, only to be captured again, this time by Gandalf and Aragorn who wanted to question him about the Ring before placing him in elven custody in Mirkwood. Escaping from there, Gollum hid out in Moria where he first picked up the trail of the Fellowship.
