That depends on which metal and which acid. Hydrogen is certainly the gas most commonly given off. But if it's an oxidising acid, such as nitric acid or chloric acid, you won't get much hydrogen. Concentrated nitric acid gives off nitrogen dioxide (NO2) with most metals. If you reduce the concentration of the nitric acid to between 50% - 25%, the main gaseous product will be nitric oxide (NO). Even sulphuric acid, which is only weakly oxidising, will produce mostly sulphur dioxide (SO2) with many metals, if it is hot and concentrated.
And, of course, with non-oxidising acids, there will be no reaction at all, if the metal concerned is more electronegative than hydrogen. (Copper is a good example.)

I read that when you replace H in an acid by a metal, you get a salt. So the bubbles going out is to Hydrogen I think.

Yes, mixing acid with metals can produce gas.

When I was a kid we would mix aluminum foil and hydrochloric acid in a bottle and attach a balloon that filled with hydrogen and would float and explode hugely when lit with a match.

Zn+HCl=ZnCl2+H2
so hydrogen
