Default path of moon and tilt

I've read that the moon tilt's is about 1.5 degrees on its axis.

Are the moon and earth on the same plane of revolution around the sun?
It doesn't look like it from pics, but that may be just because of
earth's 23 degree tilt.

Are all the planets on the same plane of revolution?

The Moon has a small wobble, and its axis of revolution is very
close to perpendicular to its plane of orbit.

No. Check out "Axial Tilt" for Uranus.

Which in turn is inclined about 5° to the ecliptic.

That's rotation about its axis, not revolution around the Sun. Uranus's
orbital inclination (found two rows above axal tilt in the table) is
very similar to the Earth's. The orbits of all the major (non-dwarf)
planets lie within about 5° of a common plane; Mercury's orbit is the
most inclined to the Earth's, at 7°, all the other inclinations being
less than half of that.

If this number were 0 degrees, I believe lunar and solar eclipses
would be common. Every month, or every day?

As to the Moon's axial tilt, you can easily measure it for yourself.

Or which angle of 0 would create the most frequent lunar and solar
eclipses.
