They look like the geese I have ...Africans is what I was told. I had heard they can be rather unpleasant. I have pinned my gander several times just to remind him who is top goose in this flock.
He will raise his head & honk but has never offered to come at me. They all as a chorus tend to honk & talk a lot.. Good luck ...or good eating whichever seems most prudent to you.
I am posting a pic of my geese for you to compare... the middle goose /gander? in your series of pics looks just like my gander.
