They all join the Earth's north and south poles. Actually, that's enough
to define all of them, and I can't think of another property.
No. All of them do but two. The latitude lines at 90 degrees North and South actually coincide with the intersection of all longitudinal lines. So technically, because they coincide, they do not form any angle.
-- All lines of longitude meet at the north and south poles. -- No two lines of latitude ever meet or cross each other. -- Every line of longitude crosses every line of latitude. -- Every line of latitude crosses every line of longitude. -- There are an infinite number of each kind, so there are an infinite number of places where a line of longitude crosses a line of latitude. (That's kind of the whole idea of the system.)
Lines of longitude converge at the poles. They are all great circles that intersect at the North and South Poles and are equidistant from each other. This convergence creates lines of longitude that are all equal in length.
They cross at the two poles.
The north and south poles are at 90° latitude, and ALL longitudes meet there so longitude at the poles is irrelevant. Honestly, it's much easier to discuss these things if you forget about "lines".
All lines of constant latitude are parallel to all others,but no two lines of constant longitude are parallel.

The two tropics are lines of latitude at 23°26′13.0″ North and South of the Equator and they intersect all lines of longitude.

Just like parallel lines on a flat surface, no two parallels of latitude ever meet.Just like non-parallel lines on a flat surface, any two meridians of longitude do meet.In fact, ALL meridians of longitude meet, at both the north and the south poles.

Two of them.

They cross at the two poles.
equator and hemisphere
All meridians of longitude begin and end at the same two points ... the north and south poles. Although they all appear parallel to each other as they cross the equator, I guess it's more comfortable to say that they're not parallel, since they all intersect.
