Everything that pulls: the lats, the upper back, the rear of the shoulder and the biceps. A row and a vertical pull do most of the work, and the curls come last, when the biceps are already warm from both.
With a full gym you can open with a heavy barbell lift and finish on cables and machines, which let you push close to failure without technique being the thing that gives out.
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. Add the smallest plate you can to the barbell lifts, and move up one pin on machines and cables once every set reaches the target.
It is the second day of a push, pull, legs rotation, the day after push. Once a week is enough for most people; twice if you run the rotation two times through.
If something is taken
Keep the same number of sets. In the app you can swap an exercise for one session without changing the program.

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 50 minutes. That is 20 working sets with the rests listed next to each exercise, plus five minutes to warm up.
Mostly the upper back, biceps and lats. The forearms, lower back, glutes and hamstrings assist. The map on this page shades each muscle by the number of sets that reach it.
A full gym: barbells, dumbbells, cables and machines.
The lats, the upper back, the traps, the rear of the shoulders, the biceps and the forearms. Anything that pulls a weight towards the body belongs here.
Either works. A deadlift is a hip hinge, so it trains the hamstrings and glutes, but the back holds the position throughout. Put it where it does not land the day after heavy squats.
