And is this hydrogen flammable?(safety reasons)

Aluminum (Al) reacts with Hydrocholoric Acid (HCl) to produce 2 byproducts Aluminum Choride and Hydrogen gas:
2Al + 6HCL ---> 2AlCl3 + 3H2
WARNING: Hydrogen gas is extremely flammable.
In general, HCl and Al are not dangerous together due to the fact that it's difficult to get a reaction going because of an adherent oxide layer on the Al atom. Once the reaction does happen, yes it can get vigorous enough to "bubble up" out of the container but it's not going to spontaneously explode.
Disclaimer: this assumes the experiement is performed in a controlled chemistry lab and under close supervision by a professional chemist. Obviously, no knowledge of chemistry may have adverse results.

Al is above H in the electromotive series. It has a higher oxidation potential. This hydrogen and all hydrogen is flammable.

6HCl + 2Al yeilds 2AlCl3 and 3H2 gas which is flammable
