Workouts for arms, biceps and triceps?

There are more to gaining muscle in your arms. Its not all weights.

Try dips, tricep extensions, pull-ups, push ups, and then add weights in. Barbell curls, butterfly weights, bench press, rowing machine, and planks. Most of this will plateau pretty quickly if you do it every day.

You have to switch up your arm workouts or else all of your gains will stop after a few weeks.

I think protein shakes will also help with muscle growing.

Only if you do it at the right time, and there is a limit to how much protein your body can use before its just stores it as fat.

My dad bought some muscle milk which i have used before i worked out a long time ago with my Cousin!

Well Muscle Milk can be either a post- or pre-workout supplement. I suggest that you don't just start taking supplements. You have to build up first. Because if you just start with a supplement, your body won't know how to react to it, and you won't get any gains, you won't necessarily gain any fat as the protein will be used, you just won't get the gains that you are looking for.

Work out without any supplements for at least 6 weeks, then start taking supplements.

Yeah i know but doesn't it take muscles longer to heal without protein shakes etc then with them?

No, protein will help your muscle fibers repair themselves a little faster but so will nitric oxide. Protein is good if you have been working out for a long period of time and you want to add a little more exceleration to your recovery. If you start with protein, you will plateau and your gains will be limited. And then you run the risk of just adding weight, which is the opposite of what you want. There is a set amount of protein that your body can use, the rest is stored as fat, so if you don't work out with it, you will just get fat.

You dont only need protein, you need a lot of different things in your body. Protein is only a small part.
