I just have a few more questions to you.

As for 1) I just want to know if punctuation is correct and if distinguish is followed by "among" or not. In 3) I just want to know if "and" is needed. In 2) and 4) I'd like you to check the word choice.

1) The interior monologue has the following features: First, it is immediate since it lacks the conventional sintax and it is free from introductory expressions; second, it doesn't follow a chronological or a logical formal order of events and time is perceived as subjective; third, the rules of punctuation are not respected. More specifically, it is necessary to distinguish (among)thre kinds of interior monologue.
2) Virginia Woolf never lets Mrs. Ramsay's flow of thoughts be without control (also: Mrs Ramsay's thoughts flow without control) and mantains grammatical and logical organization.
3) A powerful belief emerged that the races ofthe world were divided by fundamental physical and intellectual differences and (?) that some people were destined (doomed also possible?) to be led by others.
4) The Victorians thought it as a mission thrust by God to impose their superior way of life on native peoples.

More specifically, it is necessary to distinguish among the three kinds of interior monologue.

2) Virginia Woolf never lets Mrs. Ramsay's flow of thoughts be without control (also: Mrs Ramsay's thoughts flow without control) and maintains grammatical and logical organization.
Are you saying that VW lets her character's thoughts flow without control but manages to keep grammar and organization in place? Seems self-contradictory to me.

3) A powerful belief emerged that the races of the world were divided by fundamental physical and intellectual differences and that some people were destined to be ruled by others. You could use "doomed" in place of "destined" if you want to put a very dark spin on the ideas.

4) The Victorians thought it was their divine mission to impose their superior way of life on native peoples.

Several corrections/changes have been made. Be sure to compare yours and mine very carefully. And you'll probably have to rephrase #2 since I don't think it says what you want it to.

1) The punctuation in the sentence seems to be mostly correct. However, there are a couple of issues. First, "sintax" should be "syntax." Second, the phrase "among thre kinds of interior monologue" should have a comma after "among" to indicate that it is an optional phrase. So the corrected sentence would be: "More specifically, it is necessary to distinguish, among three kinds of interior monologue."

2) Both versions of the sentence are grammatically correct, but they convey slightly different meanings. The original sentence implies that Virginia Woolf ensures that Mrs. Ramsay's flow of thoughts is always controlled. The alternative version suggests that Mrs. Ramsay's thoughts naturally flow without control. It depends on the intended meaning of the sentence.

3) The sentence is mostly correct, but there is a question about the usage of the word "and" before "that." Without further context, it is difficult to determine if "and" is necessary. If the clause after "and" provides additional information about the belief, then "and" is appropriate. If the clause functions independently, it may be better to separate it into a separate sentence. For example: "A powerful belief emerged that the races of the world were divided by fundamental physical and intellectual differences. Additionally, it was believed that some people were destined to be led by others."

4) The sentence is grammatically correct, but the word choice could be improved. Instead of "thought it as," it would be more accurate to say "considered it." Additionally, instead of "a mission thrust by God," you could use "a divine mission." The revised sentence would be: "The Victorians considered it a divine mission to impose their superior way of life on native peoples."
