Latitude is an angle. Every point on Earth has a latitude that's either
between zero and 90° North, or else between zero and 90° south.
The lines that intercept latitude lines are lines of longitude.
Indonesia covers a range of latitude roughly from 5.5°N to 11°S. You're free to draw as few or as many lines in that range as you feel you'd like to see. There isn't just one official set of 'lines' that everybody has to use.
Lines of latitude run parallel to the Equator (which is zero latitude).
Namibia ranges in latitude from about 16.96° to 28.95° South. That's a range of almost exactly 12 degrees. You're welcome to draw as many parallels or 'lines' of latitude as you're comfortable with, in that range. There is no standard set of official 'lines' that everybody must use. If you look on five different maps or globes, you may very well see a different set of lines printed on each one.
Latitudes in the northern hemisphere range from zero at the equator to 90°North at the north pole. You're free to draw as few or as many lines on your map or globe within that range as you feel it ought to have.

whats the principal lines of latitude
No, lines of latitude do not intersect.

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 angle between the north pole and the south pole ... the total range of latitude ... is 180 degrees.
lines of latitude and lines of longitude are the same because they just are.
