There are two ways to do that. The first is by launching a spaceship into orbit manually and simply dropping the satellite. This is the way they do it in real life.
The second method is by using the scenario editor. The scenario editor is, as its name says, something that helps you edit scenarios. It's great for setting up missions so you (or others!) can play it later, but if you use it to bring your ship, for example, from Earth to Mars, you might consider it cheating.
Which method do you want to use? What exactly do you want to do?

Well, the easiest way is to simply select a scenario from Orbiter, that is close to what you want to have, enable the Scenario editor in your Modules Tab and then launch Orbiter.
With CTRL+F4, you can open a list of "Additional functions", where the Scenario Editor will appear in, and by opening this function, you will have the standard scenario editor (manual is in the Doc folder) of Orbiter. You can now create new vehicles in the scenario, like for example the ISS and put it into any orbit you want.
The challenge is getting the Kepler elements right, but you can use Wikipedia for a good explanation:

This is sure easier than manually editing scenario files.
But the manual way is also one option: Scenarios are simple text files. You simply select some scenarios that contain the vehicles that you would like to have in one new scenario, and then just copy and paste the individual vessel blocks of the scenarios into one file and save it under a new name. The Orbiter manual also explains the format of the scenarios, so you should have a reference there.
Code:
BEGIN_DESC
A standard DG Mk4 (left) and a scramjet DG-S (right) showing off their animations. Note the air intakes under the fuselage of the DG-S. Open the
control panel (Ctrl-Space) to play with the various elements, or hop into
the cockpit (F1) and use the mouse to operate the glider.

END_SHIPSThe second method is better, if you have no idea about Kepler elements yet, but can understand the syntax of a scenario file.
The vessels are defined between the lines "BEGIN_SHIPS" and "END_SHIPS".
Every vehicle in it is simply a block of text lines, beginning with a line in the form "<Vessel name>:<Vessel class>" or just "<Vessel class>" (Eg: Mir) and then go on until "END". Select one such block from beginning to end and copy it completely into the new scenario (But keep the blocks of the other vehicles intact, don't copy between the beginning of a vessel and "END", do that either between "END" and a new ship or after the final "END".
And important: Don't have empty lines.
I usually use the manual approach for making simple test scenarios, and use the scenario editor for the complex stuff.
Artlav did also make a Orbiter plugin, that loads the real orbit data of satellites and adds them to your current scenario. You just need the files with the so-called "Two-Line Elements" (TLE).

But all vessels created with it look like the Carina, also it is not for making new scenarios, just for giving you more traffic.

If you are talking about scenario files, they are found in the Scenarios folder.
