Hey guys help me out.

I have 3 hosting accounts, & I cant park my single domain on all the three,
so is that possible for me to park my subdomains on 2 servers & park my domain on the other.

Iam given cpanel version 9+ on all the three hosting servers, pls explain me how to do it if possible.

You can
..right.. you want me to explain how.

You have your dns servers resolve the domain and subdomains to the proper ips over the 3 servers then setup the account with that subdomain or domain.

Also, Im not sure what you mean by 'park', parking is done with an existing website.
