about eight
Depends on what you put in the crock pot. 6 quarts of soup, chili or stew will feed 12 people.
A quart is 32 ounces. I would serve 4 oz portions to 8 people.

That's about four bowls.
A quart of milk typically serves around 4 people, with each person receiving approximately 1 cup of milk.
I would guess a quart of soup feeds three. I think one can is considered a serving, and a can of soup is typically about 10 ounces. A quart is 32 ounces.
Allow about an inch at the top of the crock pot. That allows for the heat to circulate.
Depends on how hungry the first person being served at the table is. Maybe though 4 people if other dishes are served with it.
Cooked or uncooked? (the people, I mean). Your question makes no sense. How many cooked macaroni elbows in 5 quarts (volume measure, not liquid measure, OK)? Let's say there are 900 cooked macaroni elbows in a full 5 quart bowl. The serving portion is one elbow per person. You can serve 900 people. Simple. Think about your question and ask it properly next time: If you have a 5 quart bowl of cooked macaroni elbows and a serving is 1 cup, how many servings will the bowl yield?
Your question needs clarification -- a quart of what?
