It looks correct to me.

209MB is about 0.2 GB, or 0.0002 TB.

I find it easier to enable debug mode in diskutility which then lets you show hidden partitions.

Code:
defaults write com.apple.DiskUtility DUDebugMenuEnabled 1
Also the 209MB EFI is necessary it's like the boot loader that interfaces your software and firmware/hardware. http://en.wikipedia.org/wiki/Unified...ware_Interface

If you use that command in terminal, then Disk Utility app will show the hidden partitions.

Actually the EFI partition is not absolutely necessary. The EFI partition != the actual EFI. You can restore a Mac partition to a fresh hard drive with MBR partition scheme and boot it on a Mac with no EFI partition. The EFI partition IS however used for certain things, for instance EFI firmware updates will fail without it.

Yes. It is perfectly normal for your drive to have a number of other partitions: the EFI partition, the recovery partition and the "main" partition that you use.
