Is there any similarity between hydrogen bonding (important in maintaining shapes of biological molecules) and pi bonds (prohibit rotation of the molecule)?

Hydrogen bonding is an intermolecular force, while bonds are intramolecular forces and occur inside of molecules in the form of bonds. They all rely on the same fundamental forces, but are technically different things.

What are all of the kinds of intermolecular forces?

Intermolecular forces:
ionic bonding --> H-bonding --> dipole-dipole bonding --> induced dipole/London dispersion

is this ascending or descending in strength?

this is in decreasing strength. hydrogen bonds are the strongest and LDF /induced dipole forces are the weakest

pi bons are intramolecular forces that resttricts rotation where as hydrogen bonding in an intermolecular force

A Hydrogen bond is a weak bond resulting from the proton's electrostatic attraction in one atom and the electronegativity of another atom. A pi bond is a covalent bond between the unbound p-orbitals of two atom's and restricts the rotation of the atoms.

Pi bonds are also only present in double and triple bonds, since it needs an unhybridized P orbital, while hydrogen bonds are technically sigma bonds since they're only single bonds.

I don't think there is any as hydrogen bonds are sigma bonds and pi bonds are only in double+ bonds

hydrogen bonding is a type of intermolecular force whereas pi bonds are the means by which the bond is formed. However, I'm not sure hydrogen bonding and pi bonds coexist as hydrogen only forms single bond hydrogen bonds whereas pi bonds are only present in double and triple bonds

Hydrogen Bonds and pi ponds really have nothing to do with each other in my knowledge.
