No. The equator is tilted about 23.5° from the plane of the Earth's orbit.

No. They orbit in a flat plane in line with Neptune's equator.
It's because the Earth's axis is tilted. Therefore the plane of the equator is tilted (at about 23.5 degrees) away from the plane of the Earth's orbit. Therefore the celestial equator is tilted away from the ecliptic.
The moon's equator is inclined 6.7 degrees with respect to its orbit. (Rotation axis is 83.3 degrees from orbital plane.) The moon's orbit is inclined 5.1 degrees with respect to the ecliptic plane ... the plane of the earth's orbit.
Any time a planet has rings they will be aligned with the planet's equator. Uranus' axis is highly tilted such that its rings are almost perpendicular to its orbit.
All satellites pass the equator. Twice every orbit.

A satellite in an equatorial orbit flies along the plane of the Earth's equator. If an orbit does not lie at an equatorial orbit, then it will not remain at a fixed state.
I'm not sure what you mean by "a stable orbit". The Earth's center of mass ... nominally the Earth's center ... always lies in the plane of any Earth orbit, so the ground track of the orbit must either cross the equator or coincide with it.
That plane contains what is called the celestial equator, the projection into space of earth's equator. Not to be confused with the ecliptic, which is the plane containing earth's orbit around the sun.
There is no set inclination of a satellites orbit to the earth's equator. Once in space, the spin of the earth or where it's poles happen to be become irrelevant to the satellite. Many satellites like spy and weather satellites orbit over the two poles (north and south) while communication satellites are placed in orbit directly above the equator at a height that is synchronised with the earth's orbit. This way they stay permanently above the same place on the equator and do not APPEAR to move at all.
No. They orbit in a flat plane in line with Neptune's equator.
If its orbit is tilted relative to the equator,it will move over different parts of the earth.
Any orbit of the Earth must have its center at the Earth's center. So there are two choices for any Earth satellite: -- Orbit above the equator, never crossing any land that isn't on the equator, and never visible to people who aren't located close to the equator, or else -- revolve in an orbit that's inclined to the equator, sooner or later crossing every point on Earth that lies within the N/S latitudes equal to its inclination, and eventually visible to the majority of Earth's population. A satellite can't, for example, orbit entirely above the Tropic of Cancer, or the Arctic Circle. It must either cross the equator twice in each orbit, or else stay permanently above the equator.
Geostationary satellites.Geostationary satellites.
GEOSTATIONARY=GEO+STATIONARY MEANS EARTH+FIXED POINT thus geostationary orbit is orbit around the earth is in the same plane as that defined by the earths equator at an altitude of 22,236 miles (35,786 km eg say satellite such that it appears to be stationary to the orbit of the earth above the equator all day long. where as sun synchronous orbit occurs from north to south pole as the earth rotates
In geosynchronous orbit, it's always somewhere over the same meridian of longitude.In geostationary orbit, it's always over the same point on the equator.
