If your story uses just the Human Torch then use the individual one. But if it's about all of the Fantastic Four then stick to just the Fantastic Four tag.
Now I may be wrong, but as far as I understand, those three tags you mention are rather different things: 'Growth' is used for growing taller/muscle growth akin to what Banner does when he changes into the Hulk, usually used in stories where the woman become
huge and muscular and the guys become scrawny playthings; 'Body Modification' is mainly about the changing of boobs, ass and dick size; and 'Transformation' is reserved for the more odd things like animal features, ie girl grows cat ears, tail and whiskers.
As for the final thing you mentioned, if it's in the storyline but not the part you're writing, then don't worry about the tag. But if you have characters talking about how they're going to fuck their siblings the next time they see them, then you should
have the incest tag even though the act hasn't occured yet.
