How do I easily switch between different devices and can I also use multiple screens?

Or
2

I have the following devices: 2 laptops (only one has a USB-C connection, both have an HDMI connection) and 1 Surface (micro display port connection).

I would like to use a switch / button etc. To switch between my devices mentioned above (I would then like to be able to use 3 screens, mouse, keyboard, etc. For the selected device).

Can someone help me or recommend something here?

For this you would need a so-called KVM switch. These devices are available in a wide variety of designs. Kan can use the same monitor for several video inputs (PCs) or "switch" the USB interfaces directly with one another at the push of a button.

Can I then use 3 screens and extend them?

Because I only have one HDMI output here.
