I don't know what you mean by this usage. If you quote the opinions of other authors in the middle of your paper, you can of course quote them in a standardized way. So if the method is standardized, of course it can be used.

After all, the significance of publishing our paper is to discuss with all scholars in the industry, and then let the academic community make progress. We can't quote other people's papers, so how can we make academic progress? If you win other people's opinions in your paper, add some quotation marks and you can quote them.

It is absolutely impossible for you to copy other people's papers. This is first and foremost an academic misconduct and academic fraud, and this mentality must be abandoned.

It depends on your situation. If it is formal, normal quotation is certainly possible, but if you want to take the road of plagiarism, it is absolutely impossible.
