Did They Logged In

I just check server logs today and found this:
Seems like someone else logged in to my server via FTP.

Since i only limited my IP to login to server Via FTP, SSH... using APF
But now, beside my IP, there's a few of connections from different IPs.

- Does that mean they logged in?
- What is the localhost login there?
