If you are referring to different sounds for different apps. Please follow the below steps.
Open device Settings >> Apps >> Now in App info, under App Settings tap on Notifications. This will open the notifications with various Categories depending on the app you select >> Tap on Sounds/Ringtone and select which sound/Ringtone you want to set.
Thanks. I have gone through more of my apps and have found that setting. The apps I checked previously to my post do not have that available. I may choose to use a different app for those purposes. Again thank you.
