There are five people visible in the image. They appear to be engaged in construction work. The person on the left is wearing a white shirt and appears to be working on a crane. The person next to them is also dressed in white and seems to be involved in the same task. The third person, standing slightly behind the first two, is wearing a blue shirt and is also working with the crane. The fourth person, located further back, is wearing a yellow shirt and is likely overseeing the construction process. The fifth person, standing at the far right, is wearing a black shirt and is holding a tool, possibly a level or a measuring instrument.
