I have created a web which is a sub web of the "Host Web"(In terms of App).
I want to get data from a list which is part of that sub web into my SharePoint hosted App.
How can I get it?

There's a section on working with list items, which will allow you to retrieve items in a list; you'll need to work with the url, and either the list title or GUID.
