Have you had a read through the complete documentation? That should hopefully answer most of your questions. If you are using Excel files, make sure your agent has access to them (access to network drive, stored in repo etc)

Azure DevOps has some predefined variables that you can use.
$(Build.SourcesDirectory) is the local path on the agent where your source code files are downloaded, so you could use that for "Path to readyapi test project"
