A flat press for the whole chest, an incline press for the upper part, a fly for the stretch, dips for the lower part and push-ups to finish it off.
Dumbbells make each side carry its own weight, so a stronger arm or leg cannot cover for the other, and they travel through a longer range than a bar allows.
Sets per muscle. A muscle that only assists in an exercise counts half.
How to run it
Before the first exercise, do two lighter sets of it: one at about half your working weight and one at three quarters. Rest for the time shown next to each exercise; the heavy lifts at the top need more than the smaller ones at the end.
Aim to finish each set with one or two reps left in you. If every set reaches its target easily, the session is too light. Dumbbells go up in big steps. When the next pair is too heavy, add a rep to every set first, and move up once you are two or three reps over the target.
Once or twice a week, with at least two days between sessions. If you also train shoulders and triceps on their own, keep one of those days well away from this one.

Logging is free for good. The first 14 days also include Pro, where a coach reviews each session and suggests the weights for the next one. No card needed.
Questions
About 40 minutes. That is 16 working sets with the rests listed next to each exercise, plus five minutes to warm up.
Mostly the chest, shoulders and triceps. The abs assist. The map on this page shades each muscle by the number of sets that reach it.
A pair of dumbbells and a bench.
Three to five. One flat press, one incline press and one fly cover the whole muscle; more exercises than that mostly repeat the same movement.
Press on an incline. A bench at about 30 degrees, or feet-raised push-ups without one, moves the work to the upper fibres.
