There is no difference between the terms 'paper' and 'article'. A research paper is one where an original study has been performed. A review paper may be either a narrative review, a systematic review or a meta-analysis. A narrative review is like a book chapter: it explains a topic in detail based on previously published research.
If it is a research article, it should it should be written in the IMRaD format (Introduction, Methods, Results, and Discussion). These are known as empirical studies. Literature reviews (meta-analyses), theoretical articles, methodological articles, and case studies may also be considered scholarly.
