Showing only two posts on home page. (front page is selected as home)

Hello everyone,

I am a beginner level word press developer. I have installed a theme and customized so many things into the site including styles, css, html and widgets.

Now I am stacked in an issue where only two latest posts are showing on home page. But I want to show more than 2 posts on home page.

Any help from you guys will be very much appreciated.

Thank you
