I just read a comment to a book blog post where someone asked the following question: Are there any fictional characters you'd like to be friends with in real life?
That started me thinking, because that's far from clear-cut. Most characters I like aren't necessarily so nice and reliable that you'd like to get to know them in real life. That meant I really had to dig deep to find a few (compared to how many characters I really like). Here is a list of the ones I thought of right now (I'm sure there are more).
From LOTR:
Radagast and Eowyn (others too)
Gladys from A Sudden Wild Magic
Conrad from Conrad's Fate
both books by Diana Wynne Jones
Bix from Dinotopia by James Gurney
Tenar from The Tombs of Atuan (Earthsea series) by Ursula K LeGuin
Tuppence from Partners in Crime by Agatha Christie
Like I mentioned before, I'm sure I'll think of more later, but these will do for now.
