Answers to those specific questions
They’re all read-only, but here’s where things live:

1. /snap/nextcoud/current/conf/httpd.conf.
   You can restart the Apache server using snapd's tooling:
   sudo snap restart nextcloud.apache
2. /snap/nextcloud/current/config/php/php.ini
   There isn’t a php daemon as such in this configuration - looks like it is run per-request, so you wouldn’t even need to restart Apache to apply any changes. Just reload/refresh the page.
3. /snap/nextcloud/current/htdocs/config/config.php
   Nextcloud doesn’t have a daemon at all, it’s all just php. See above.
4. /snap/nextcloud/current/htdocs/
