One google email on two phones with different phone numbers how doI delete without losing apps.
One can remove Google Account from a device without any loss of apps installed.

However it is necessary to add atleast one Google Account in a device to enable downloading apps from playstore or using any Google App within the device.

To remove - Open Settings/Accounts/Google

Tap on Google account you want to remove and tap 3 dots on the upper right corner of the screen. Choose 'Remove Account'.

And remember to add an Google Account if you don't have any logged in after removing existing one.
