Just as individual pigs differ in size, so do their lungs. Their lungs are rather small for the size of their bodies, so this can lead to respiratory problems for some pigs.
Both lungs are different sizes
Without lungs, pigs would not be able to breath air, and will die from asphyxiation.
Lungs
Pig lungs are divided into seven lobes between two different lungs. In the right lung is larger and divided into apical, cardiac, diaphragmatic and intermediate. The left lung is smaller and does not have an intermediate lobe.

There is no limit, assuming you have a big enough cage, to how many guinea pigs of different sexes and/or sizes you can physically put together. I am not sure if you will get baby guinea pigs out of it though.
If you are studying fetal pigs, their lungs will appear dense and compact. This is because they have never taken a breath.
