Yes, you can engage and contract your stomach muscles while doing sit-ups to strengthen and tone your core.
A good diet + exercise = flat stomach So while push ups can help in making a flat stomach, which in fact is just low body fat, it will be useless if proper nutrition and other exercise, ex. weightlifting and cardio, is not utilized.
It is very difficult to lose weight in a targeted area like the stomach. The most effective way to get an attractive stomach is to focus on overall fat loss while toneing abdonminal muscles. Exercises like situps and crunches can help tone, while vigorous cardio exercise helps with overall fat loss.
A relaxed stomach is when the muscles are not engaged or tightened, while a flexed stomach is when the muscles are contracted and tightened.
Crunches build muscles while situps build abdominal muscles. Each workout is important based on individual needs.

Not really. It is possible to tone muscles in the stomach area while losing fat overall. This will result in a better looking stomach and, eventually, six-pack-abs.
The muscles that are in your arms
Sit ups help develop your abdominal muscles, but it takes a lot of time... There are many different ways to do sit ups, including laying in the traditional position of sit ups raising your legs and pulling them into your stomach, all the while keeping a fixed upper body position. It tends to be those who have a slimmer frame who have the visible evidence of situps, if you are larger then the muscle will simply develop under the fat, so it's always a good idea to include cardio whenever doing sit ups.
Yes. The throat muscles pull food toward the stomach regardless of which way you are positioned.
