5 axis tool length offsets (Fanuc G43.1 and Haas G143) use the tool length in the tool table and can be used with the tool axis orthogonal to the XY plane.
G43 and G43.1 can be used in one program if you set up the parameters to make sure the offsets are applied in the same direction (ie positive or negative application direction).
