Oh sorry about that, below is what command i inserted:

tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1 htb default 30
tc class add dev eth0 parent 1: classid 1:2 htb rate 120Kbit burst 15k
tc class add dev eth0 parent 1:2 classid 1:11 htb rate 6Kbit ceil 120Kbit
burst 15k
tc qdisc add dev eth0 parent 1:11 handle 11 sfq perturb 10
tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip dst
192=2E168=2E1=2E1 classid 1:11
tc class add dev eth0 parent 1:2 classid 1:12 htb rate 6Kbit ceil 120Kbit
burst 15k
tc qdisc add dev eth0 parent 1:12 handle 12 sfq perturb 10
tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip dst
192=2E168=2E1=2E2 classid 1:12
tc class add dev eth0 parent 1:2 classid 1:13 htb rate 6Kbit ceil 120Kbit
burst 15k
tc qdisc add dev eth0 parent 1:13 handle 13 sfq perturb 10
tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip dst
192=2E168=2E1=2E3 classid 1:13
tc class add dev eth0 parent 1:2 classid 1:14 htb rate 6Kbit ceil 120Kbit
burst 15k
tc qdisc add dev eth0 parent 1:14 handle 14 sfq perturb 10
tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip dst
192=2E168=2E1=2E4 classid 1:14

I ve tried those, and it worked, all hosts able to borrow bandwidth from
parent class (120Kbit), but when any host start to download with DAP
(download manager) that can consume high bandwidth, it can borrow 120Kbit
from parent class and the speed wont decrease as the other hosts up and as=
k
for more bandwidth=2E

Any idea why ?

Yes :)
Remove the burst parameter.  Htb will calculate the minimal burst for you.
And 6kbit is too low.  You have 4 classes and you have 120kbit so give each
class a rate of 120/4 = 30kbit.
And prio 100 for a filter is useless.  Prio in filters is only to determine
the order how the filters are checked.  In your case, you can remove each
time prio 100.  This will not change anything, it's only a clean up if the
commands.
