I had two primary partitions (/dev/sda1 and /dev/sda2). Then I created an extended partition to segment it into logical partitions.

After I had typed fdisk /dev/sda and n (add a new partition) the following message appeared.

p primary (2 primary, 1 extended, 1 free)

l logical (numbered from 5)

What does 1 free mean?

With a traditional Master boot record, you only get four slots for primary or extended partitions. You already have two primary partitions, and one extended (in which you can create logical partitions). So there's only one slot left in the MBR for an additional primary partition.
