É só marcar para baixar apenas ir a /var/cache/apt/archives copiar todos os pacotes de lá e colar na mesma pasta mencionada lá atrás e mandar o Synaptic dessa vez instalar os pacotes.
Mas dai, se na primeira pergunta que fiz, a reposta for "não", provavelmente você tera erros de dependências, ou então criar uma ISO customizada com tudo o que você precisa nela e instalar nessas máquinas há possibilidades, porém sem internet a coisa muda de figura.
Esperto ter sido útil de alguma forma a seu questionamento.
