I read it only works with 70-200 mm panasonic lens but the 24-70 is the same size 80mm? Will it not work with that lens?
Teleconverters are typically only compatible with tele zoom lenses and not wide to medium zooms. In addition the converter will not seat into the rear of the 24-70mm lens due to the rear lens element.

Since you loose 2 f stops, using on the Panasonic ...
Since you loose 2 f stops, using on the Panasonic Lumix 70-200 F/4 is equivalent to f/11?
That is incorrect. When using the Panasonic DMW-STC20 Lumix S 2x Teleconverter on the Panasonic Lumix S PRO 70-200mm f/4 O.I.S. Lens, the focal length of the lens is multiplied by 2x while the maximum aperture of the lens is reduced by two (2) f-stops. As such, using the Panasonic DMW-STC20 Lumix S 2x Teleconverter on the Panasonic Lumix S PRO 70-200mm f/4 O.I.S. Lens would make the lens the equivalent of a 140-400mm f/8 lens.

I see that many people have success with that TC on a Sigma 150-600mm. Is there a possibility that it also works with 100-400?
It is not listed as compatible. Only way to know is to try it out. Even if it works you may get other issues such as error messages. I wouldn't recommend it.
