ummmm, galaxies can have galaxies in them unless they combine, also, we don't know, the universe is infinite and we have ye to see beyond our local galaxy cluster... sorry but that is an impossible question (although if the universe is infinite then nothing is quite impossible...)

universe is largest. universe is made up of billions of galaxies.

`Solar system` is the smallest. then `Galaxy`, then `Universe` is the largest.

It is the largest galaxy in our local group, but there are larger galaxies elsewhere in the universe.
A Galaxy Group: Is the smallest grouping and usually contains less than 50 galaxies.A Galaxy Cluster: Is larger than a group and usually contains between 50 to 1,000 galaxies.A Supercluster: Is the largest collection of galaxies and will contain many groups and clusters.I think you mean group of galaxies. A group of galaxies is groups and clusters are the largest known gravitationally bound objects to have arisen thus far in the process of cosmic structure formation. They form the densest part of the large scale structure of the universe.

Higgs Boson -> Galaxy Filaments.
The largest THING in the universe is the universe itself. Then would come DARK ENERGY. Third is DARK MATTER and lastly would be clusters of galaxies.
