"Lines of longitude" are conceptual, not physical; there can be as many as we want. For example, there are 3600 "seconds of longitude" between each degree of longitude. That's 60 minutes of arc per degree, and 60 seconds of arc per minute.
One degree of angle is equal to 3,600 seconds of angle.
The Prime Meridian ... the line that marks zero longitude ... goes through both Spain and France. But it's not correct to say that a whole country is on any one longitude. Spain covers all longitudes from 9.29° west to 3.31° east of the zero line. France covers all longitudes from 4.77° west to 8.23° east of the zero line.
