Hydrogen IS a metal, just not at room temperature and at the normal atmospheric pressure of 1atm.
I say this because if you were to cool a sample of hydrogen to almost absolute zero (0 degrees Kelvin) and subjected it to high pressure it would form Metallic Hydrogen which exhibits all the properties of a metal, it would exhibit metallic bonding of its electron with other atoms, it would be a conductor of electricity and heat, etc,
In fact Hydrogen is just a gassified metal, because if you heat up a sample of Lead (Pb) high enough to cause it to evaporate, it is still a metal just like hydrogen!

It's placed on the metal side of the periodic table due to it's atomic number, and mass. It's not a part of the Alkali metals

It is placed on the farthest left column because of its valence. Like the metals below it, Hydrogen only has one electron in its outermost shell. Helium is in the 18th family and not the second because it has a full shell (s orbitals can only hold 2 electrons, if you want to get fancy).

I'm not sure but I would think because its ion has a positive charge. the elements on the left of the periodic table have postitive ionic charges, and those on the right are negative. the transition metals vary.

Because "metal" in chemical sense does not refer to "metallic appareance", but its capacity to accept electrons due to electronic configuration of the atom.
That is the reason that appears above, Lithium, Sodium, Cesium, etc.

because it doesnt exibit metallic properties and exists as a gas at room tempurature
