Yes; all compounds possess London dispersion forces between their molecules, because all compounds contain electrons. However, in the case of H2CO, this will not be the strongest intermolecular force. The strongest will be dipole-dipole interaction, because H2CO is a polar molecule.
Yes it does and in liquid it also has hydrogen bonds.
There are London forces present between helium molecules.
Pretty much everything has London dispersion forces, so yes.
Yes.
Yes, the London dispersion force is very weak.

London Dispersion Forces
Yes, the London dispersion force is very weak.
no
Dipole-Dipole and covalent sigma bond forces.
The only intermolecular forces in this long hydrocarbon will be dispersion forces.
dispersion force (London)
Dipole-dipole and dispersion
The London dispersion force is considered as the weakest intermolecular force. The production of an instantaneous dipole in London dispersion is only temporary.
