No, that is not true. They are molecules that have both hydrophobic and hydrophilic parts.
NO! the requirement is for hydrogen to be bonded to a very electronegative atom such as oxygen or fluorine. Alkanes, e.g. C2H6, contain C-H bonds and there are no hydrogen bonds.
Yes, H2O contain two hydrogen atoms and one oxygen atom.

hydrogen bonding
No. Molecules are made of atoms, not the other way around. E.G. A MOLECULE OF WATER IS MADE OF 2 HYDROGEN ATOMS BONDED TO A CENTRAL OXYGEN ATOM. SO HERE, 1 MOLECULE HAS 3 ATOMS.

Any atom that is not carbon or hydrogen.
No, a Hydrogen atom does not contain any neutrons. It only has one proton and one electron.
No, it is a molecules composed of a nitrogen atom bonded to three hydrogen atoms.
