Hi I am trying to dual boot Fedora and XP, I ran the live usb Fedora xfce 17 installer with already there were 2 ntfs windows partitions in the system. I just created a root(ext4)checked the forced to be primary partition box, swap(ext4) as a standard partitions, but when I created 5th home partition, it turned out as an extended partition. As I have only 3 primary partitions (2 windows and 1 Fedora root), how come the 5th turned as a extended?

You can only have four primary partitions. You can make one of those be an "extended partition", which can contain a large number of "logical" partitions.

You had two primary partitions to start, and then wanted to add three more partitions. Since that's more than four, the only way that can work is for there to be an extended partition.

It's also worth nothing that there's really no downside to having these things on logical partitions.

I'm still counting five, here — two ntfs, root (/), swap, and home (/home). Am I missing something?

This will be true in Ubuntu too, since it's an ancient limitation on PCs from the early days of DOS. We just may be exposing it to you in an uglier way.

My recommendation is to get rid of all of the partitions except for the nfs ones. Then, put all of your unpartitioned space into one, big extended partition and create all of your Linux partitions inside it as logical partitions. There's no downside to it, and it keeps things simple for you. Also, you don't need to bother making your / partition bootable because Linux doesn't care; that's an old MS-DOS artifact from the Bad Old Days when the boot loader needed that to know which partition to boot from.

Yes. There's no reason you can't put / on a logical partition inside an extended one. If there's unpartitioned space after your extended one, you can create a new primary as long as there's no more than four of them, total, but why bother? Neither Windows nor Linux will care one way or the other.
