it is said that full frame aperture equivalent of 2.8 to aps-c is 4.2. does it mean that shutter speed of aps-c is one stop slower that full frame on the same aperture? given the same focal length equivalent e.g. aps-c 23mm and ff 35mm.

No, just the opposite. It won’t matter which body you put the lens on, it will operate the same way. The “equivalent” you’re chasing only pertains to FOV
