If you downloaded a cloud image from ubuntu repo, the username is "ubuntu". You can access the virtual machine using Key pair only. Make sure that the permission of the key is 0600.

ssh -i yourkey.pem ubuntu@<floating-ip-of-the-vm>

You can access the VNC console via browser only. You have to setup, VNC server in the VM to access remotely using a client.
