Can I use different version of Rails with different apps?

So I've got a couple of apps running locally and on Heroku which I made using Rails 4.1.8 and Ruby 2.1.5p273.

In my Gemfile of one app it says 

gem 'rails', '4.1.8'

I'm about to start working through Michael Hartl's Rails tutorial and he recommends installing the same version of Rails that he uses in the tutorial: 4.2.0.rc3

Can I run gem install rails -v 4.2.0.rc3 in my console and not cause any problems with my existing applications that I'm working on?

Yes-if you specify in your Gemfile which version you are using it should be fine! You can also install rvm to manage different versions of Ruby and Rails from the command line:
