The sentence using the correct capitalization is the third:
"The Red Cross is a liaison for the families of soldiers stationed in other countries, acting as a go-between for separated spouses, parents and children."
Neither <em>liaison</em> nor <em>soldiers</em> need to be capitalized, since they are only common nouns, while the <em>Red Cross</em> is the proper noun of an institution and as such, it needs to have each word capitalized.

The correct sentence is "Are Mei-Ling and us singing together today's?" We want to keep the sentences clean and using "we" wouldn't make sense.
