To start developing an ionic project:
Prereqs
Include Git for Windows for windows which is what I assume you are using based on the image in your question. After you install Git (and npm which you also stated was installed) go to the directory where you want to create the project and run the following.
npm install -g cordovanpm install -g ionicionic start appName blankcd appNameionic platform add androidionic build androidionic emulate android
Also you can run in web browser using ionic serve or a web browser with iOS and Android using ionic serve --lab
If you want to emulate the Android device, make sure you have a system_image installed of the device you want. Guide here to do that.
EDIT:
Run npm --v and you should see the version you are running, if not then npm isn't installed correctly. Install it globally and run the process again.

To add to Sam5487 answer. If you are behind corporate proxy, then you should first these commands with appropriate changes.
npm config set proxy http://proxy.company.com:8080
npm config set https-proxy http://proxy.company.com:8080
Then
npm install -g cordova
npm install -g ionic
ionic start <your app name>blank --type=ionic1
ionic cordova platform add android
For web browser testing you can use
ionic serve
After you are happy with your changes
ionic build android
ionic emulate android
