Excellent, you show initiative. Most good qmail resources can be found by
either following links from qmail.org, or by doing a Google search.

Perfectly normal.

Yes, that's exactly it. They're messages for which a temporary error occurred
on at least one recipient. If all recipients have either succeeded or failed
permanently, the message will be bounced by qmail in short order and will be
removed from the queue.

Temporary errors; failure to connect or 4xx codes from remote mail servers.
Local deliveries can also be deferred in some circumstances.

Yes; `man qmail-tcpok` and `man qmail-send` will tell you how. However, it's
not necessary. qmail uses a backoff algorithm that works surprisingly well.
The retry schedule is detailed in Dave Sill's excellent "Life with qmail".

See above.
