For all practical purposes, yes. But the earth is not a perfect oblate spheroid, although it is very close. If you want to get very picky, there may be technical differences in their lengths just because of the unevenness of the earth's surface in places. Meridians that cross only or mostly water would arguably be of the shortest possible length. Those crossing mountain ranges or otherwise quite varied terrain would be technically longer.
No
I don't see the need for that - all meridians (for example, at sea level) should have the same length.
-- All meridians of longitude have the same length ... they all join the north and south poles. -- Each parallel of north latitude has the same length as the parallel at the equal south latitude, but no other one.
There's a simple answer: The earth is a sphere and the parallels are, well, parallel to each other. So obviously the ones closer to the poles are shorter than the ones closest to the Ecuator. As for the meridians all meet at one point ehich are the poles, so they are all the same length.
No. All of the meridians merge in a single point at the poles.

Meridians of longitude; parallels of latitude. Remember that meridians are all the same length (20,000 km) and that they meet at the poles. Parallels are, well, parallel, and are different lengths, the longest being the Equator.
No, not all meridians have the same length or the same beginning and end points. Meridians are imaginary lines on the Earth's surface that run from the North Pole to the South Pole. The prime meridian, which passes through Greenwich, England, is considered the starting point for measuring longitude.

Lines of longitude are called meridians and converge at the poles. The length of a meridian is determined by the circumference of the Earth, making all lines of longitude the same length. This is because the Earth's shape is an oblate spheroid, with meridians meeting at the poles and being widest at the equator.
as all the places on the same longitude have their noon at the same time
-- Parallels are associated with latitudes. Meridians are associated with longitudes. -- Parallels are parallel, and no tweo parallels intersect. All meridians intersect all other meridians, at two places. -- Every point on a parallel has the same latitude. Every point on a meridian has the same longitude. -- Every parallel in the same hemisphere has a different length. Every meridian on Earth has the same length. -- Every parallel is a full circle. Every meridian is a semi-circle. -- Every parallel crosses all longitudes. Every meridian crosses all latitudes. -- The distance between two parallels is the same at every longitude. The distance between two meridians depends on the latitude where it's measured. -- To cross all parallels, you only have to travel 12,000 miles. To cross all meridians, you have to travel 24,000 miles.
The longest parallel of latitude is the one defined as 'zero degrees', known as the "Equator". All meridians of longitude have the same length ... 1/2 of the earth's polar circumference.
The meridians meet at the poles, which are the points on Earth's surface where the lines of longitude converge. At the North Pole, all lines of longitude meet, and the same is true for the South Pole.
All meridians of longitude converge (meet) at the north and south poles.
