I don't really think you can install 4 or more OSs on a harddrive.
A harddisk can  have either 4 primary partitions or 3 primarys and 1
extended. I suppose the most stable configuration you might get is one
primary for each OS, while extended stores data as Windows can only use
its own primary and the extended.
