There is no set amount of press ups that a person is allowed to do in a day. A person can do as many press ups as their body will allow them to do. You do not want to over do it because you could strain your muscles.

Press ups help biceps, lats, stomach, and triceps I personally think that press ups work more then push ups and I am a strengthening coach for a high school
none he never existed.
This really depends on the individual performing the exercise. Explosive press ups are great as a high impact workout, really impacting the muscles. Normal press ups are great as well. Alternate the two for a maximum workout.
It depends on how good of shape you are in if your not very healthy yes it is bad if you are fit and a athlete its good

push ups and pull ups
A very good question indeed. Using dumbbells (I'm assuming you mean dumbbell bench presses) allows you to increase the weight meaning you can exert a greater force with your muscles, meaning bigger pecs. However press ups develop what is called functional strength, which is basically strength you can do in day to day tasks. Also press ups work your core. I would suggest using both to get the benefits of both
