In your terminal, type:
scp [email protected]:foobar.txt /local/dir
replacing the username, host, remote filename, and local directory as appropriate.
If you want to access EC2 (or other service that requires authenticating with a private key), use the -i option:
scp -i key_file.pem [email protected]:/remote/dir/foobar.txt /local/dir

You can do this with the scp command. scp uses the SSH protocol to copy files across system by extending the syntax of cp.
Copy something from another system to this system:
scp username@hostname:/path/to/remote/file /path/to/local/file
Copy something from this system to some other system:
scp /path/to/local/file username@hostname:/path/to/remote/file
Copy something from some system to some other system:
scp username1@hostname1:/path/to/file username2@hostname2:/path/to/other/file
