I presume by that you mean that it shows the dependencies for several
versions of rails. In which case it means you have several versions
of rails installed. Your application will use whichever version you
specify in Gemfile.

rails -v shows you which version is in use.
If you need to manage multiple versions I advise using rvm. Others
like rbenv I believe.

gem list will show you all the versions of gems that are installed.

If you have not already done so then, as you are a beginner with
rails, I suggest working right through a good tutorial such as
railstutorial.org (which is free to use online). That will show you
the basics of rails.
