Hi,
I tried following suggestion give by Jorden, still when I try to connect
on the 11th line I get message saying no tun device available.

I had to changed the above to "tun??)" then it let me make "tun10"
device. The entry in the "/dev" directory has correct minor number (10),
but when I try to connect on the 11th line that is "tun10" it says no
tun device available.

I tried doing that but still it gave incorrect minor number
crw------- 1 uucp dialer 52, 0 Aug 16 21:52 tuna
^^^
not correct
Output of the "netstat -ain" shows me that I have 16 tun device compiled.
Here is the output of the "netstat -ain"

Another thing to notice in the output of the "netstat -ain" is that
normally when the device is not used I see "*" next to the device,
but for tun10 - tun15 I don't see that too. Is it because there is
no space or some other problem?
