Not really. Service medals usually aren't presented, although they can be. You actually don't simultaneously qualify for these. For example, by coming on to active duty, you qualify for the NDSM. By being in a deployable (not training) unit, you qualify for the GWOT Service Medal. The GWOT Expeditionary Medal, Iraq and Afghan Campaign medals depend on when and where you were in each authorized area. See below for when/where etc.
You qualify for the National Defense Medal for honorable active service for any period between 27 June 1950 and 27 July 1954, both dates inclusive; between 1 January 1961 and 14 August 1974, both dates inclusive; between 2 August 1990 and 30 November 1995; and from 11 September 2001 to a date to be determined. Any member of the United States Coast Guard or the Reserve or Guard Forces of the Armed Forces who, between 1 January 1961 and 14 August 1974, became eligible for award of either the Armed Forces Expeditionary Medal or the Vietnam Service Medal or between 2 August 1990 and 30 November 1995, became
eligible for award of the Southwest Asia Service Medal will be eligible for award of the NDSM. Cadets of the U.S. Military Academy are eligible for the NDSM, during any of the inclusive periods listed above, upon completion of the swearing-in ceremonies as a cadet.

c. Service members qualified for the Global War on Terrorism Expeditionary Medal by reasons of service between 19 March 2003 and 28 February 2005, in an area for which the Iraq Campaign Medal was subsequently authorized, will remain qualified for that medal. Upon application, any such service member may be awarded the Iraq Campaign Medal in lieu of the Global War on Terrorism Expeditionary Medal for such service. No service member will be entitled to both medals for the same act, achievement or period of service.
d. Service members must have been assigned, attached, or mobilized to units operating in the area of eligibility for

The Southwest Asia service medal hasn't been awarded since 1995. That was for the Gulf War, and ensuing operations in and around the CENTCOM theater till 95.
No - they are not all for the same thing.
