One approach is to use a mask as a path, twirl open your text > Path Options > Path and choose the mask as the path. Copy the mask to the other text layers. You can create a “parent” mask that controls the child masks also, so you only have to adjust one path. Just copy the first mask to the child layers, open up the mask properties, alt-click on “mask path” and pick whip that to your “parent” mask path.
I made an example project that should help you start out: 5641_curvetext.zip
Also, under the obsolete effects is a Path Text effect that will accomplish what you want, but if you use that, you are giving up a lot of control and animation properties that you have with the text tool.
