The point is, you've got a physical disk which has 250GB of 'space'.
This you have broken down into multiple partitions as shown by 'df -h' & 'fdisk -l'
Each partition is effectively its own disk.
df -h output
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 151G 8.5G 135G 6% /
tmpfs 990M 520K 989M 1% /dev/shm
/dev/sda1 194M 23M 162M 13% /boot
/dev/sda2 77G 72G 1.9G 98% /home

1. your /home partition is nearly full, which is what the msg is in fact saying if you read it
2. you don't need 150Gb for root partition (aka '/'); ideally you should probably re-partition to use e.g. 50GB for '/' and the rest for home.
(in actual fact the programs, cfgs etc stored in '/' should fit inside 10 (maybe 20 ) GB, but as it sits, you're also going to have all your logs under there as well.
