5 exercises is amply sufficient. For aesthetics, frequency is more important than quantity : it's better to have 2 exercises 2 times per week than 5 exercises 1 time per week (if your sets stay close to muscular failure of course).
Yeah I am doing Push Pull Leg Day, each of them twice a week.
So all of my exercises have 10 reps.
The first two exercises 4 sets and the others ones currently 3 sets ( I am too exhausted for more) only abs I do 5 sets of 15
So for example Pull day:
4x10 Lat Pulldowns
4x10 Cable rows (seated) close grip
4x10 T Bar rows wide grip
5x15 Cable Crunches
3x10 Dumbbells curls
It's perfectly fine if you are beginner/intermediate.
Remember to stay close to muscular failure (if your exercises form is safe), keep a progressive overload and take rest days/deload weeks.
Don't hesitate to do some variations in your training : more or less volume, more or less intensity...
