Things really haven't changed altogether that much. I can't quite tell what that is next to your Grandfather, but I still use the old trick of hanging the camera bag from the tripod to give it extra weight and stability. I don't recognise the camera. The one on the tripod near the center may be a press camera, like a Crown Graphic 4X5. They had a viewfinder along one edge, and a rangefinder along the other. A TLR of some sort over on the right. Hope the camera gives you good service, and makes your Grandfather proud.
