I guess these notes from the HP Fortran 8.0 Ref Manual gives
some hints :

The following copyrighted standard and specification documents
contain precise descriptions of many of the features found in
HP Fortran:

- American National Standard Programming Language FORTRAN,
   ANSI X3.9-1978

- American National Standard Programming Language Fortran 90,
   ANSI X3.198-1992
   (This Standard is equivalent to: International Standards
   Organization Programming Language Fortran, ISO/IEC 1539:1991 (E).)

- American National Standard Programming Language Fortran 95,
   ANSI X3J3/96-007
   (This Standard is equivalent to: International Standards
   Organization Programming Language Fortran, ISO/IEC 1539-1:1997 (E).)

So, F90=1992 and F95=1997.

According to the HP-Fortran 8.0 Ref Manual :

 > Fortran 95 includes Fortran 90 and most features of FORTRAN 77.
 > Fortran 90 is a superset that includes FORTRAN 77.
 > HP Fortran fully supports the Fortran 95, Fortran 90,

> On ALPHA?  On Itanium?

Both, according to the same manual.
