Latitude ranges:
Zero to 90 degrees north
Zero to 90 degrees south
Longitude ranges:
Zero to 180 degrees east
Zero to 180 degrees west
There are 180 degrees of east longitude and 180 degrees of west longitude, for a grand total of 360 degrees of longitude around the Earth. You're free to draw as few or as many 'lines' through that range on your map or globe as you feel will make you comfortable. There is no standard set of 'lines' that everone is required to use.
The highest longitude lines are the prime meridian at 0 degrees longitude and the 180 degrees longitude line. These lines mark the starting point for longitude measurements to the east and west, respectively.
Any meridian of longitude between about 53.66 and 73.55 degrees west passes through Argentina. There are an infinite number of possibilities in that range.
Iran spans more than 19 degrees of longitude. It occupies the range of longitude roughly from 44.04° to 63.33° East. Any longitude you choose in that range passes through territory of Iran. You're welcome to draw as few or as many lines on your map as you wish in that range. There's no standard set of them that everyone must use.
Mongolia's latitude ranges from approximately 41 to 52 degrees north, and its longitude ranges from approximately 87 to 120 degrees east. The capital city, Ulaanbaatar, is located at a latitude of around 47.92 degrees north and a longitude of around 106.92 degrees east.
They are called the lines of longitude. Lines of longitude range from 0 degrees on the prime meridian to 180 degrees.

They are lines of longitude, not latitude, but 60° East longitude is approximately correct for the 1600-mile long range.
Latitude and longitude are angles that describe the location of a point on the Earth's surface. Longitudes range from zero to 180 degrees east or west. Latitudes range from zero to 90 degrees north or south. There are no official 'lines'. Some maps or globes have some lines printed on them to show where a few latitudes and longitudes are, and other maps and globes have no lines at all printed on them. I have mapping software that can print 324,000 latitude lines and 648,000 longitude lines if I want them, but I have never needed them yet.
The approximate latitude and longitude lines for, Alexandria Egypt are 31 degrees E. and 31 degrees W.

The African continent extends across a longitude range from 17.5° west to 51.3° east. You're welcome to draw as many or as few lines in that range as suit your comfort, and name them too if you're moved to do that. The only meridian of special note in that range is the Prime Meridian, at zero longitude.
