Heres a better routine.
Work harder than yesterday. The one you have one is basically just a tutorial, probably given to you to teach you the basic movements.
It is smarter to push yourself more every time you train... You train to do get better not to do the same thing over and over again.
Pick your own goals and work it up.
Want big arms? Weighted pull ups, do more everytime
Want big legs? Squats, do more everytime..
You can start off with 3 sets as warm up with light weight and 5 heavy sets... Weight doesn't matter as long as you feel it is actually hard and pushing your limits, it must feel heavy for you.
Don't waste time doing too many exercises, maybe do some calf raises or maybe face-pulls... But keep it at 3 exercises max....
Only advanced athletes who do it for a job need many exercises, unless you want to be competing for money, you need only 2 or 3 exercises.
How many repetitions? As many as you can.
How much weight? As much as you can without hurting yourself.
