I want to fetch the data from various repositories. In the available plugins for logstash I did not find plugins for Google Drive, Sharepoint, JIRA, Yammer. I want to know whether they are in development or already available and I overlooked. Also, is it possible to develop custom plugins for these repositories on our own.

Yes, of course. The Logstash documentation contains a section on writing plugins.
