I have Windows 98 on my home PC which does not have the game Sapce
Cadet Pinball.  Newer versions come with the game Space Cadet Pinball.
  Is the game available for (free) download from a reliable web site? 
If the game is not free from a reliable web site, does Microsoft sell
the game and can it be downloaded?

This web site says the download from another site is not reliable:
Windows 95: Space Cadet 3d pinball... The one at
www.geocities.com/NapaValley/8985/free.html does not download
properly. ... Space Cadet Pinball was never included with Win95. ...

This one first brings up an ad and then you have to "sign up":

Download.com for 3-D Space Cadet Pinball It will be listed as: 3-D
Pinball and is a 2.59 MB zipped file. It is 3.78 MB unzipped. ...

You'll need the installation instructions for it to run on Windows 98

Do you have access to a computer that contains the game? I was once
able to transfer the game using a 1.44 floppy, by zipping the relevant
game files and copying it onto the disk. After copying, unzipping and
arranging the files and folder for it, I was able to play it at once.
I believe I excluded some files which were nothing but score files, so
the scores are reset, but the game runs.

hehehe~ I like the game Space Cadet Pinball too
Space Cadet Pinball used to come with Windows 95 PLUS!
