I forgot to include the following statements. I really hope you can correct them as well.
8)The wind goes away from her house or the wind left her house?
9)The omniscient narrator can be divided into obtrusive and unobtrusive (is it correct? Or would be better to say “the omniscient narrator can be obtrusive or unobtrusive.
10)A Metonymy is the substitution of a word for another with which it is closely connected.
11)An omniscient narrator has an unlimited point of view OR He tells the story from an unlimited point of view. An internal narrator is also a first-person narrator. (Is it always true?). An omniscient narrator knows everything about the story (and not all about?)
12)An external narrator is or stands outside the story/is a voice outside the story (which are correct?) who or which tells (about: is about necessary?) events he does not take part in.
Sure, here are the corrections for each statement:
8) "Does the wind go away from her house or did the wind leave her house?"
9) "The omniscient narrator can be categorized as either obtrusive or unobtrusive. Alternatively, you could say 'The omniscient narrator can either be obtrusive or unobtrusive.'"
10) A Metonymy is "the substitution of a word for another word that is closely associated with it."
11) "An omniscient narrator has an unlimited point of view. Alternatively, you could say 'An omniscient narrator tells the story from an unlimited point of view.' Regarding the internal narrator, it is typically a first-person narrator, but this may not always be the case." As for the second part, "An omniscient narrator knows everything about the story."
12) "An external narrator stands outside the story or is a voice outside the story. Alternatively, you could say 'An external narrator is someone who is not part of the story, but tells (about: you can omit 'about') events that he does not take part in.'"
