This is a group portrait, but it's a good representation of a candid photo because everyone in the photo is not paying attention to the camera, and doing daily tasks. Its a humble photo because no one is trying to look better, and they're not prepared.
Posed
A posed photo is when the model poses and their expression, and body language makes the photo seem less natural than it could be. Posed images can also give more of a dramatic tone to the image as well as seem fake.
