Two equivalent Lewis structures are needed to describe the bonding in SO42- due to resonance. In one Lewis structure, two double bonds are formed between sulfur and oxygen atoms, while in the other structure, one double bond and one single bond are present. The actual structure of SO42- is a combination of these resonance structures.
Two equivalent Lewis structures are necessary to describe the bonding in O3. These structures involve adding a double bond between each pair of oxygen atoms in alternate arrangements.

A single Lewis structure can be used to represent the bonding in SeF2O.
None. All the bonds are single bonds as is normal for a fluorine compound
