The lines are called the Prime Meridian and the International Date Line. The Prime Meridian marks 0 degrees longitude and runs through Greenwich, England, while the International Date Line marks the transition between calendar days and generally follows the 180 degrees meridian.
A complete globe, including Earth, always has 360 degrees. There can be an infinite number of longitudinal lines because longitudinal lines are imaginary constructs and not physical features of Earth itself, so the number of degrees between those longitudinal lines is dependent on the number of longitudinal lines, assuming the longitudinal lines are equidistant. To calculate the number of degrees between these equidistant longitudinal lines, divide 360 degrees by the number of longitudinal lines. A model globe of Earth is typically given 36 lines of longitude. Using the calculation given above, the angle between adjacent longitudinal lines is 360 degrees divided by 36 lines of longitude, or 10 degrees. If 24 lines of longitude are used to represent the 24 time zones, the angle between adjacent longitudinal lines is 360 degrees divided by 24 lines of longitude, or 15 degrees.
Longitudinal lines themselves are imaginary constructs, having no real width, and therefore, no angle to measure. The angle between longitudinal lines on a globe depend on how many longitudinal lines are used to encircle the globe. Assuming that all longitudinal lines are equidistant, the angle can be found by dividing 360 degrees by the number of longitudinal lines. Typically, a globe will be given 36 lines of longitude, so the angle between longitudinal lines is equal to 360 degrees divided by 36 lines, or 10 degrees.
The Equator is the latitude line with a given value of 0-degrees. There Equator runs completely around the Earth. There are 360-longitude lines that intersect the Equator.

The poles are just points at 90 degrees north and south latitiude.
The lines of latitiude are also called 'parallels'.

First you go to where the prime meridian (0 degrees line of longitude) and the equator (0 degrees line of latitiude) cross, which is just south of Ghana in Africa. From there you go east or west according to the first coordinate and follow that around the earth to the correct line of longitude. Then you go north or south from that point to whatever the latitude indicates. The lines are usually shown on the globe at 15 degree intervals so you will need to interpolate (approximate) the position between the lines.
Given two lines, each is perpendicular to the other if the angles formed at the vertex are 90 degrees.
The Equator is the latitude line with a given value of 0-degrees. There Equator runs completely around the Earth. There are 360-longitude lines that intersect the Equator.
"Lines of Latitude" and "parallels" are both used. Please note that the "lines" are imaginary; you'll never see one on the ground. Just on a map.
Lines that cross each other at 90 degrees are perpendicular lines.
