Each of these games has their own max FOV，under this premise，am I need to convert all scope sens with mdh0?

I'm not quite sure what you mean, but you should stick to the same conversion method for scopes regardless of hipfire FOV if that's what you're asking.

I mean the max fov is different for each game, here is an instance, I use mdh0 to convert my 105 fov(max actual vfov 105 degrees) sens of bf4 to 1.7 cl_fovscale( max actual vfov 99.309056 degrees) sens of apex, the essence of different scopes is different fov. Since I can convert between different scopes like this, can I convert between different games like this?

Absolutely, this works exactly like with the scopes; you keep the same tracking speed.
