The halides in higher oxidation state posses high charge and are smaller in size as compared to the lower oxidation state halides.
Thus, in higher oxidation halides the charge/radius ratio is higher which contribute to the increase in polarisation and consequently these are more covalent.

When Tin and chlorine combine it creates either:-SnCl2, called tin(II) chloride, stannous chloride. This is molecular in the gas phase and forms polymeric covalent chains in the solid (mp. 247 anhydrous form)), but dissolves to form Sn2+ which may hydrolyse. The electronegativity difference is only 1.2 so it would be expected to be covalent rather than ionic.A covalent molecular compound SnCl4, tin(IV) chloride, stannic chloride, tin tetrachloride.

No, silicon can form only four covalent bonds.
Polar covalent. C is more electronegative than Si.
Because oxygen is much more electronegative than carbon, the bonding in CO (carbon monoxide) is a polar covalent.
Nucleic acids would be one example of a covalent compound with more than 3 elements. Proteins have more than 3 elements as well. Many organic compounds do, it is quite common.
Carbon is the element tht will form only covalent compound.
