Yes, it is possible to stream 4 or more Android screens to one laptop. One way to achieve this is by using screen mirroring software that allows multiple devices to connect and stream their screens to the laptop. Some examples of such software include Reflector, AirServer, and Mirroring360. Another option is to use a hardware solution such as a video capture card that can capture the screens of multiple Android devices and display them on the laptop. However, the hardware solution can be more expensive and may require additional setup and configuration.
