How can I check if my old iPhone activity is visible on my new iPhone?

If I take an old phone and unlock it and connect it to WiFi and open apps, will the user of the new phone know it?

If the old iPhone is using the same Apple Account, and those apps can sync the changes to other devices, yes.

Using a device having the same credentials without consent is not a good idea, in my opinion.
