Two or more planets- same orbit?

[Diamonds]

It would be nice if there were 3 planets at the same orbit with the earth? But is it really possible?

When I tried to find a clue I checked some values of Saturn Ring system. They may be 100 km Wide but only 30 meters thick.  Why so ? Is it because of the inclanation?

Pluto and Charon are binary system but seem to have some problems not to stay in same kind of inclanation than other planets.

What about the Galaxy? Are there planets at almost same orbit?

When I Google there is an answer that 2 planets same orbit is o.k.

But is it really so I doubt. If not Keplers second law prevent that there might be other reasons like perhaps the INCLANATION?

I see no reason why two or more planets cannot be in the same orbit, as long as they are separated enough to where each ones' gravity is not interfering with the others'. Make sense?

There are several scenarios whereby two planets occupy the same orbit. If two planets pass close to each other in orbit, one can disturb the other, resulting in a massive orbit change. These two planets can collide, one of them can be thrown away, and the other can even be thrown into their central star.

Three or more Jupiters will probably not work due to the immense amounts of gravity, even if they are evenly spaced.
