The bottom line is you want 1 1/2 pounds of foods, not counting desserts and beverages, total per person. 5-8 ounces ready to eat meats total- with this many choices you probably want to go for 8- people eat more when there are more entrees. The rest from your sides.

Use my tables for 100 to plan the side dishes, allowing 4/5 or 80% of the amount for 100. This will cover your salads, veg, rice and potatoes.

You have an awful lot of entrees- pork, ham, meats, goulash, tuna casserole and chhicken. Is there a reason for this many? The usual number of entrees for a group this size is 2 or 3, maybe 4 for a larger group. You might consider simplifying your menu.
