let me confirm what i get from your write;
You have ubuntu system installed varios application on it. Then you
want install the same version ubuntu and the same application on other
machine. You want to install application on the other machine without
connecting to internet again. Straight forward use file from previus
installed system. I'am correct.

If it's correct so you can use local repository. Make local repository
from your old insstalled ubuntu+application the use that local repo to
install program on new installed ubuntu.
