I have a 960GB
External USB SSD and I have MacBook Air.
I would like to know if is it possible to install, macOS Catalina 320GB
, Windows 10 320GB
, Linux CentOS 7 320GB
in the same External HD.
I don’t know how to find a guide to know how to install these sequentially.

You should be possible to install, macOS Catalina 320GB, Windows 10 320GB, Linux CentOS 7 320GB in the same external SSD. You probably will have to use the CLI to install Windows 10 to the external SSD.
Below is a suggested GPT partitioning for the drive.

for CentOS 7I would suggest creating partitions 1 through 4 before installing any operating systems. Leave free space where partitions 5 and 6 will eventually reside. Next, install macOS followed by Windows 10. Finally, install CentOS. Here, I would let CentOS create its own partitions (5 and 6) in the free space.
I do not know what your experience is with respect to installing operating systems. I can expand on this answer if necessary.
