Hi, Michael! Welcome to
RTP!
I'm not a lawyer, but my first gut reaction to your question is:
1: NO, the photos belong to the photographer
2: MAYBE: You would need the photographer's permission or at least give him photo credit.
3: YES
I'm operating on a premise that if I stand on a public street and take pictures of cars going by, the owners of those cars do not have any rights to the photos. Or if I stopped my car on a country road and took photos of a farmer's cows, he cannot claim any kind of ownership or rights to the pictures.
