Please I want to download some app in my phone and it telling me to upgrade to iOS 16 I don’t understand that

Apple expects that your device is running the most recent version of iOS available for your device. Many apps will not run on an older version of iOS. When that is the case, you are advised to update your device's operating system.

M1 Mac mini, macOS 14.4.1;  Watch, series 7 GPS/cellular, watchOS 10.4; iPhone 12 Pro, iOS 17.4.1; TV 4th Gen, tvOS 17.4; HomePods, audioOS 17.4 and Airport Express w/ Airplay 2

Depends on the model of the phone. Go to Settings > General > About, and post what is listed under:

• iOS Version
• Model Name

Go to Settings>General>Software Update.

If your phone can be updated, the update will be offered there for you to approve and install.

The developer of the app chooses which iOS versions they want to support. If your device is not capable of running the needed version for that app, then you will need to purchase a newer phone.
