Carbon (18%)
Hydrogen (10%)
Nitrogen (3%)
Calcium (1.5%)
Phosphorus (1.0%)
Potassium (0.35%)
Sulfur (0.25%)
Sodium (0.15%)
Magnesium (0.05%)
Copper, Zinc, Selenium, Molybdenum, Fluorine, Chlorine, Iodine, Manganese, Cobalt, Iron (0.70%)
Lithium, Strontium, Aluminum, Silicon, Lead, Vanadium, Arsenic, Bromine (trace amounts)

Obviously I know all of these are found naturally on Earth, but which of them exist in space or on other planets? Which of them are found in gas clouds and meteorites ect?

I know hydrogen, nitrogen, sulfur and iron are found in gas cloud and the cores of planets, but what else?

I am not sure what your question is. From all we know all these elements are present in all the Universe. In different ratios, as what we see on Earth is a product of processes that concentrated heavier elements, but they are all everywhere.

Well what I mean is, has magnesium, calcium, phosphorus, potassium ect been found anywhere else apart from on Earth?

To put it simply, does the stuff that makes up gas clouds, meteorites and space dust share any common elements that the human body has?

All of them! Apart from hydrogen, a small amount of helium, and a tiny bit of lithium, which were formed following the Big Bang, all other elements were created in stars or during supernovae. See the Wikipedia article on nucleosynthesis to learn more.

So we are quite literally star dust? Humbling to know.

Yes.

Adds a perspective, doesn't it?
