On average, about 2 medium-sized Roma tomatoes diced will yield approximately 1 cup. It's always best to measure diced tomatoes using a measuring cup for accuracy.
Depnding whether or not you prefer a more paste like texture than the chunky texture of diced tomatos then you may.
Stewed tomatoes are cooked or stewed and diced tomatoes are cut into pieces but all tomatoes remain tomatoes no matter what you do to them. Not true at all. During processing of diced tomatoes a firmer less ripe tomato is used to hold up for a smaller cut, while stewed tomatoes are from fruit that is vine ripened longer and much more flavorful. Different tomatoes and lengths of ripening vary for all canned products which affects flavor.

No, diced are more chunky chunks of tomatoes, where as crushed looks more like a sauce to me. I guess it's preference to. I like to use diced with my lasagna but some people prefer crushed.

Diced tomatoes
Yes, depending on the dish. If you are making lasagne for example, you can substitute with just tomato paste. You might want to add more onion and herbs for flavour. If you were going to substitute paste for tomatoes that are displayed on the dish, then I'd make something else !
