Hi kowal108,
I see that you are having an issue with locating some devices in iCloud using Find My iPhone. I also see that you have linked the best article for troubleshooting this issue:
iCloud: Troubleshooting Find My iPhone, iPad, iPod touch, or Mac - Apple Support

Did you happen to already try the steps for your issue, located below?
This can occur if:
- The date on your device is incorrect. Choose Settings > General > Date & Time to check and set the date.
- Your iOS device is currently off or not connected to a data network (Edge, 3 or 4G, or Wi-Fi). Wait a few minutes and try again.
- Your iPad (Wi-Fi only), iPod Touch, or Mac is currently off or not connected to a Wi-Fi network.
- Location Services is not enabled on your iPhone, iPad, or iPod Touch (Settings > Privacy) or on your Mac (Date & Time) preferences. Learn more about Location Services on your Mac:
- You are located in a country where Apple does not offer this feature. This feature may not be available in all countries due to technical limitations or local law.
If you have tried those steps, did all of your devices appear when you checked Find My Device on iCloud.com from a computer?
Thanks for coming to the Apple Support Communities!
Regards,
Braden
