I need to find different chemical compositions of stars like Sirius, Altair, Pollux, Castor, Betelgeuse and other ones.

Stars are not wildly variable in composition.
In fact, they are almost entirely hydrogen:
90% hydrogen (by number of atoms)
10% helium
tiny traces of heavy elements (everything else)
You might be able to find some of your above mentioned stars at:

Mostly hydrogen - about 97% or more. The other elements include helium, lithium, carbon, oxygen, etc, all the way down to iron (in smaller amounts the further you go down the periodic table). But wikipedia will have more detailed information - just not on the specific stars, most likely. Just stars in general.

it is 90 percent of hydrogen and 10 percent helium.
