Well let’s start with what is structured data. According to Google,
“Google Search works hard to understand the content of a page. You can help us by providing explicit clues about the meaning of a page to Google by including structured data on the page. Structured data is a standardised format for providing information about a page and classifying the page content; for example, on a recipe page, what are the ingredients, the cooking time and temperature, the calories, and so on.”
Essentially you tell Google what to look for, what the page is about and Google returns those elements as results.

So essentially all the above results can be achieved with Google structured data.
Now there various kinds of structured data rich snippets, list is below –

Book actions that enable users to buy the book that they find directly from Search results.
Navigation that indicates the page’s position in the site hierarchy.
Rich results that display in a sequential list or gallery. Most often, the carousel features articles from a single site (known as a host carousel). The carousel can also feature a variety of publishers, like Top stories. This feature works best when used in combination with one of the following features: Article, Recipe, Course, Restaurant, Movie.
Educational courses that appear in a provider-specific list. Courses can include the course title, provider, and a short description.
