Yes.
No, sigma bonds are formed by the overlap of atomic orbitals, typically between two atoms. Lone pairs are not involved in the formation of sigma bonds. Lone pairs are non-bonding pairs of electrons that are not involved in bonding.
Lone-pair electrons, Bonded pairs of electrons
Such pairs of electrons are called as lone pairs.
A lone pair of electrons can affect the molecular shape by repelling bonded pairs of electrons, causing distortions in the molecule's geometry. This can lead to changes in bond angles and overall molecular shape.
There are two lone pairs on the sulfur atom in SO2Cl2. The sulfur atom has a total of 6 valence electrons, with two bonds to oxygen atoms and two bonds to chlorine atoms. This leaves two lone pairs of electrons on the sulfur atom.
There are four electrons, which is two pair.
Germanium (Ge) has four valence electrons and can form four bonds by sharing these electrons. In its most common oxidation state, +4, germanium typically forms four covalent bonds with other atoms, resulting in no lone pairs. However, in certain compounds or coordination complexes, it can exhibit lone pairs depending on its hybridization and bonding environment.

two bonds and eight lone pairs
Boron typically forms three bonds and has no lone pairs due to its electron configuration.
