Latitudes and longitudes cross the whole Earth. The Equator crosses only those places close to the middle.
No. The lines on maps are imaginary - they do not exist.
The equator passes through Africa, South America, and Asia. The Prime Meridian passes through Europe and Africa. The Tropics of Capricorn and Cancer pass through Africa, Australia, South America, and Asia.
Africa is the only continent that's crossedby both of those imaginary lines.
Many imaginary lines run through India. Latitudes and longitudes for instance.
Every meridian of longitude between 5.14° West and 1.77° East crosses both France and the UK. Any longitude in this range may be represented by a 'line'. There are an infinite number of such lines, and they're all imaginary.
All four of those imaginary lines cross Africa.
All of those imaginary lines cross territory in Africa.
-- Most of the imaginary lines on the surface are parallels of latitude, meridians of longitude, political boundaries, and shipping routes. -- The imaginary lines through the center of the globe are the axis and diameters.
Each of those lines crosses some part of Africa.
