I'm using QGIS 3.10.0 A Coruna. As you see in the picture, I have an unregular grid with some buildings on them. I would like to fill out all the other rectangles between the points with a polygon automatically. That means every 4 points should create a seperate polygon. Is there a possibility to do so?

You could create a polygon that completely covers your study area, then use a Difference tool with the buildings layer as the Overlay Layer. Then use Split With Lines using the line layer as the Overlay Layer.
