You will have to check that for every journal individually, there may even be an "article type" differentiation. For letters, five figures are a typical upper limit, while for regular papers there may even be no limit at all, but quite often reviewers may ask you to focus on the important ones and move some of them to the supplement.

Every journal has an "Information for Authors" section on its website. Elsevier typically allows 3 to 5 figures, but the exact limit can vary depending on the specific journal you are submitting to within Elsevier. To find out the precise guidelines, be sure to check the "Information for Authors" for the particular journal you are targeting. If you face restrictions on the number of figures, consider combining multiple components into a single figure. For example, you can create one figure that includes several parts labeled a, b, c, and d, allowing you to display 4 figures as a single image.
