It shouldn't cause any problems. I have substituted soy milk for regular milk in many recipes without any problems. You usually can't even taste the difference.
Because you are substituting a number for a variable. Like substituting salt for sugar in a cake recipe. Although you really shouldn't do the latter.
It varies per recipe, and for what you are substituting it in for. Usually, it is 1 can or 8 ounces or so, for the average recipe.
Dumplings may be made with suet by substituting finely chopped suet for whatever fat is called for in the recipe.
If your recipe calls for cornstarch but you do not have any on hand, you can easily use flour. If the recipe calls for 1 tbsp. of cornstarch, use 2 tbsp. of all-purpose flour.
Yes Assuming that you are substituting "regular" oats for some sort of flavored oats...or oats with some spice additive.....
yes because cornstarch is usually used to make things thicker its depending on what your recipe says

Almost any recipe can be made to a healthy, or healthier, version. Substituting healthier oils in place of butter, adding fresh vegetables, and using lean meats are great ways to make any recipe healthier.
Some people suggest substituting glycerin with an unflavored oil (same proportion as the glycerin). You can usually miss the glycerin out of the recipe without it resulting in an extremely different outcome (as long as the glycerin was only a small proportion of the recipe).
There is no one single recipe for people with heart problems that would be considered 'healthy'. People with heart problems should check with their doctors for diet guidelines that would be appropriate for their individual conditions.
That depends on what you're substituting it in. If its baking, I wouldn't do it. Heavy cream has a much higher fat content, and will throw off a baking recipe. If you're just substituting it in mashed potatoes, or soup, or a sauce, I'd use it 1:1, one cup for one cup. You'll just end up with a richer tasting, smoother end product with better mouth feel, that's all.
It depends on why you are "substituting" the beef. In a recipe, no. As a dietary substitute, perhaps. Both beef and cottage cheese are forms of protein, dietarily you can eat cottage cheese rather than beef. Trying to use it in a recipe instead of beef is a potential disaster.
