[Element]

when i hold shift and right click the bin file and select command window..i put minetest.exe server Element's Creative Server serve i get...

--address <value> --config <value> --disable- unittests --enable-unittests --gameid <value> --go --help --info --logfile <value> --map-dir <value> --name <value> --password <value> --port <value> --random-input --server --speedtests --trace --verbose --videomodes --world <value> --worldname <value>

what do these mean and are these used to create a multiplayer server

It gives you the list of possible command line arguments because you're doing it wrong (misspelled some argument?).

[Element]

then how do i do it

[Element]

i opened a command window and typed in minetest.exe --server --worldname my first world

This is another way to do it and its much easier!
I assume you use windows.

Make a shortcut to minetest.exe.
Right-click > Properties on the shortcut. Then put quotes around the shortcut's path and add:
--server --worldname TheWorld'sName to the end of the path.
Replace "TheWorld'sName" with the world you want to use.
(Make sure it is not a single player map, if it is navigate to it and delete players/singleplayer and auth.txt)
The path should now look like this:
"C://programfiles/minetest/bin/minetest.exe" --server --worldname TheWorld'sName
When you open the shortcut, just Minetest's Console (The black window with text in) will open, and you have a server.

To change settings go to minetest.config and add things from config example.
