I need help to migrate my Free G-suite account to my Synology NAS

I need help to migrate my Legacy Free G-suite account to Synology NAS.

I need to move my old:
- emails from gmail
- google Drive files
- Google Photos
until my Google account is empty.

The email accounts should be fully functional and will be hosted on my NAS.

The old emails should be imported and accessible in my newly hosted accounts.

The new emails should be accessible from my smartphone and laptop using Gmail app.
