HTTP/0.9 was first formalized in the HTTP/1.0 spec. HTTP/0.9 does not literally appear in the HTTP/0.9 protocol.

HTTP/1.0 is the first major version of HTTP.

HTTP/1.1 revises HTTP/1.0, and is currently defined by six RFCs.

HTTP/2 is the second major version of HTTP. It defines no minor versions, so minor version 0 is implied.

HTTP/3 is the third major version of HTTP. It defines no minor versions, so minor version 0 is implied.
