According to APA standards, if my paragraph is from one source and only one source, and the sentences that i paraphrsed are from different parts of the source. (one sentence of my paragraph is from top part of the article, and another is in the middle and so on...)How many times do I cite it? Do i cite it only once? Or cite it for every sentence? Or cite it when the sentence that i paraphrase is from different section of the source/article?

This is the best reference I have found that covers all aspects of writing in accordance with APA guidelines:

Be sure to scroll down and read these sections:
== Section I. C (especially the link in 1.)
== Section I. F
== Section II. G

There may be additional sections and/or links that will help.

Here is another. Check on all, including the ones that indicata APA:

According to APA standards, if you have a paragraph that is paraphrased from different parts of one source, you only need to cite it once at the end of the paragraph. In APA format, you typically include the author's last name and the year of publication in parentheses at the end of the paragraph.

For example, if your paragraph contains sentences that were paraphrased from different sections of an article by John Smith published in 2020, you would cite it at the end of the paragraph like this: (Smith, 2020).

You do not need to cite the source for each individual sentence within the paragraph unless you are directly quoting or paraphrasing a specific sentence or phrase from a different source.
