Create a config file

Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa

Host github-sokada
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_sokada

Try it

# if you have fatal: remote origin already exists.
git remote rm origin
# add origin
git remote add origin git@github-sokada:shinokadagist/Grade6
git push -u origin master

# check your git config list
git config --list

Now you can git push normally.git push origin master.
