Please, how can I generate topology on a picture of my face 
…? Like the ones below
Practice, practice, practice, practice, practice… ( no that’s not a joke). Since ever 2D-artists spent years of reading the form and set light and shadows in the correct places to give the impression of a similar face. Also it isn’t just paint over some good grid and call it topology this has to be on the corect place.
If you do really mean you own face (that one which is looking on this screne) then you could put some different little colored sticky pads on it (or non permanet markers) and make a photo from front and side… to match the positions of the different colored points…
…or you pay for somehting like this Facebuilder for Blender… for example.
