1. Tharkun. (Hark in a mirror image of nut).
2. Incanus (sun + Cain).
Both names of Gandalf, I think?
I'm wondering if it's one of those passwords where each clue connects to something, and that something is the password (like the 'Tolkien' one you did a while ago). Because I think that:
3. Is Stormcrow (co + worm + str) earthquaked/shaken up ... (Although at first I was using the standard shortening of street - St - and got as far as StormCOW.
... and that the password might be GANDALF. (It was only when 'Stormcrow' started to form that I thought this, though. Thought Tharkun and Incanus was a coincidence at first).
4. Olorin (Ol (small old) + R + Oin).
I think 5 might be Mithrandir - but the only bit I can make work is 'deer' for 'dir' - 'ran' being the wrong tense for 'jogs.'
