You should have replaced the switches with like switches. yes, you'll have
2-three ways and one 4-way. WHERE the 4-way is , is anybodys guess. It's
the one with 4 wires on it.

My "L"-shaped hallway has a light switch at the end of each leg, a
switch at the intersection of the legs and a ceiling-light the middle
of each leg.

Originally, the ceiling-lights could be turned on/off from each
switch.

I've replaced the original switches with new switches but now only one
switch operates the ceiling-lights.

Should a three-way switch be installed at each end of the hallway and
the four-way switch be installed at the intersection of the legs? If
the answer is "NO", where should the various switches be installed?

How to I determine what wire gets connected to each terminal of each
switch?
