Welcome! Hopefully we can get you straightened out!

GnuPG 1.4.9 is a bit out of date. https://gpgtools.org/ should have a
more recent version, but it seems that it will only work back to Mac OS
X 10.6, not 10.5.
Can you upgrade to a newer version of Mac OS X? 10.5 is quite old and
reached end-of-life in 2011.
You might find
to be of some interest.

It's possible that Mac OS X 10.5 does not have gpg, openssl, or sha1sum
installed. I'm not familiar with systems that old.
However, it appears that the system does have a means of calculating MD5
checksums. You should be able to run the following command from a terminal:
Alternatively, if the Mac has GPG installed already (I know that newer
versions of Mac OS X do, but I'm not sure about 10.5), you can run the
following from the terminal:
gpg --print-md MD5 /Users/alain1/Desktop/GnuPG1.4.9.dmg

What happens if you run the command without the square brackets () or
the single quotes (')?
openssl md5 /Users/alain1/Desktop/GnuPG1.4.9.dmg

OpenSSL is installed in newer Mac OS X systems, but might not be
installed on 10.5. If it's not installed, you could install it but
that's typically not a trivial thing to do.
Check if it's installed by running:
from the terminal.
As for your other questions, I'm not sure. Hopefully someone else can
