Looks good so far.

I'm not sure what the first columns are. The usual command variant is 
"ps -ef" because it includes the PIDs of the parent processes. However, 
the command lines at the end of each line make sense.

Yes. The area queries will work after the first complete loop of 
rules_loop.sh.

The most convenient way is probably to look whether "ps -ef" yields 
different starting times for rules_loop.sh and osm3s_query --rules.

Yes, please. In general, only software that has an important reason to 
do so should run as root.

Overpass API is designed such that even the server processes and the 
clients that pose queries can be run by different users. Usually,
- dispatcher, apply_osc_to_db and rules_loop run as one normal user
- interpreter is called through a web server and can run as www-data

No, these should be all. If you want updtes then you need 
apply_osc_to_db.sh and fetch_osc.sh. Otherwise, you could stop the areas 
update loop after the first run because it does not have any addtional 
benefit.

Best regards,
