No. You can specify the log file in a server context and use the $host
variable. 

access_log /var/log/nginx/$host/access.log

Although in the wiki such practice is discouraged:
http://wiki.nginx.org/NginxHttpLogModule#access_log So yes the best
practice is to set an access log for each domain.

You have to specify a full path otherwise nginx will use a default
path. You can specify a default log file in the --http-log-path
configure option.

Yes.

Nope. It's the access log error.

See above.

Fix the access log error. Nginx isn't loading the configuration. It's using a
previous one. 

See http://wiki.nginx.org/CommandLine, the HUP signal handling to be
specific.
