Bake macaroni and cheese at 350°, uncovered in the center of the oven for about 45 to 50 minutes, or until macaroni and cheese is set.
Vegetable lasagna with cheese can keep for several months in the freezer. Once moved to the fridge, it usually goes bad within about 2 weeks.
Week in the fridge but a lot longer in the freezer
I don't know about you, but I feel worse in the freezer!
I think if you keep your hand long enough in a freezer it can get frost bite, but no. You can not get freezer burn from touching a freezer. That requires a long peorid of time.
A long time
You can keep macaroni salad for three to four days.

Macaroni and cheese isn't the healthiest option but as long as there are other foods from the different food groups eaten along with the macaroni and cheese, your lunch won't be as unhealthy. Also using real cheese instead of processed cheese can make it healthier, as well as using whole wheat noodles. Note: Your body does need carbohydrates, so macaroni provides your body with it's essential energy. Suggestion: Eat some veggies and dip on the side.
Cheese can be frozen really well. Remove the original saran wrap from the cheese (it won't freeze very well on certain types of cheese) and then wrap it in aluminum foil. Put it in a plastic bag, and it should keep for quite a while (as long as you avoid freezer burn). Hope this helps :)
