More than two 3 way switches? Possible?

We currently have a light at the top of our stairs that is controlled by a 3 way switch, one at the bottom, one at the top.
I would like to put in a second light, at the other end of the hall from the current light, that is also on the same circuit. I’d like to also put that one on the same 3 way switch, so that ideally, all 3 switches could turn on and off both lights. Is this possible?

Yes you can do that. But any switches after the first on is are 4-way switches.
This shows the logic of the 3/4 way switches.

And the links show all of the way that then can bewired.
The additional light is a separate issue. In general the simpilest way is to run a cable from the first light to the new light and parallel the connections at the first light.
