In my People and Pets album on Google Photos, it has done a very good job at identifying my friends and family, but there are a few errors (wrong person identified, two albums of the same person, friend not identified).
I cannot find a way to manually tell Google this person is Joe Bloggs etc. Is it possible? (Have tried on both the Android app and the webapp).

I'm afraid you can't tell Google who the person is, only who the person is not.
If it all works well, you'll find those photos grouped together under a different "face" that you can rename and have Google identify them again.
For the instance of a person album without a name, just open up the album and add a name. It will draw names from your contacts, but you can include a manually created name as well.
For separate albums for the same person, make sure they're spelled exactly the same. In either case, it will work best if you have a Google Contacts entry for the person. Rename one to match the contact; you should be prompted "is this the same person?" and you can essentially "merge" the albums.
