AFAIK, no. You shouldn't be able to run any of them when the device is locked.
Maybe the IMEI one is an exception - but what these codes usually do is that they start an Android activity: exactly the same as clicking an app icon in the app drawer.
The only difference is that some activities (e.g: Engineering App main activity) aren't supposed to be visible to the average smartphone user as they can have also negative outcomes if used improperly (for example, placing a call to 911 of factory resetting the device)
