It depends on the program and the type of install you do,
You can launch programs in DOSBox simply by navigating to their directory (cd dirname), and then typing the name of the program, such as WOLF3D.EXE.
Launch Services Program was created in 1998.
You can burn the client program to a CD, sure, but it's not much use to anyone without an account.
This depends very much on what you are trying to accomplish by running Windows 98 with a command prompt. If you want to launch the taskbar or open a folder, enter "explorer." If you want to launch a certain application, navigate to that program's folder (use the "cd" command to change, ie. "cd C:\Program Files\Mozilla Firefox" to change to that folder").
Launch Services Program's motto is 'Earth's Bridge to Space'.
Yes, you need a program like MagicDisc to create an ISO, bin/cue or uif of the file, then you use the program to create a virtual CD drive, and then from the program load the SW:EAW CD in to the virtual drive. You may have to reinstall the game from the virtual CD but it will run correctly. Unless of course you meant without ever owning the CD at all, in which case, assuming you torrented the game, you can get a no CD patch from many sites.
The Rosetta stone is a computer program. It will not work in a CD player. You must have a computer or laptop.
No not without an emulator program and PS1 bios
Well, you could "Explore" the CD. That will show you the files on the CD, which may not be identical to the files that get installed on the computer (for example, the CD could contain a .cab or .zip file from which the actual files are extracted).
I've read once that someone installed the program on a CD, and ran the application from the CD. How that works is beyond me.

A program can be installed off a CD or DVD, or a flash drive.
