Hi Jan Mohammad:
You are speaking Baluchi numbers correctly but if your friend is using Urdu numbers it is his mistake. Might be it is because of Urdu influence in his environment:
Anyways here is list of numbers in Urdu:
ek
do
teen
chaar
paan'ch
cheh
saat
aaT
nau
das
yaaraah /gyaraah / igyaara/ gyaaraaN (people of different accents use it differently)
baaraah
teraa
chaudah
pandrah
solah
satrah
aThaRa
unees
bees
If you are interested to learn Urdu I can provide you links of Urdu learning sites and articles.
Thanks
