I have an unmanaged switch which serves traffic belonging to different subnets. Lets say these are the subnets:
And few more subnets which I am not aware of.

I have a Linux machine having as IP on subnet. Using this machine I want to discover the arp address's of all the machines that are on different subnets. After arp address's are found, I want to discover their IP address's too. Can this be done?

You can do this with ettercap. You may want to google for "arp spoofing" and "switched sniffing" for more details.
