No because Earth is a slight doughnut shape with the bulge through
the equator, and the Moon is also orbiting around the equator
which means orbits other than equator are not stationary or stable.

Are you saying that what 7 said is ********, or that your ******** are "a
slight doughnut shape with the bulge through the equator"? :-)

Leaving aside ********, 7's description of the earth as "a doughnut shape
with a bulge at the equator" is open to misinterpretation. Doughnuts come in
two very different shapes: a ring (a toroid) and a flattened ball (an oblate
spheroid). The earth is the latter: an almost-sphere whose equatorial
diameter is a bit greater than its polar diameter - by a mere 28 km or 0.2%.

I tend to think of "doughnut" as describing a toroid. A toroidal earth would
be interesting, with a little bit in common with Terry Pratchett's Discworld
:-)

More like Larry Niven's Ringworld.

Perhaps closer to Iain M Bank's Orbital habitats.

There's clearly an opening for a series about Doughnutworld.

AIUI the Earth is an oblate spheroid.
