Hydrogen differs from Alkali metals in the following ways -
1) All Alkali Metals are typical metals but let's not forget hydrogen is a non metal.
2) All Alkali Metals are monoatomic such as Li,Na,K,etc. But hydrogen is diatomic i.e H2
3) Alkali Metals have a lower ionization enthalpy than hydrogen (1312 kJ/mol)
4) Alkali Metals Form ionic compounds i.e they exchange ions but hydrogen forms covalent compounds like HCl, H2O,etc.

Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals.
