can I buy a second package and install in the same computer with the same name? I nseed to file four or five more returns and already filed 7 of 8 in the first package

Yes, you can. When you finished the first 8 returns, you can then use another code to get 8 more returns. Please note that the CRA only allows you to file 20 returns via NETFILE per computer.
