Need some help to understand the option chain.

Looking at the yellow circle.

1. Who set the 7.70?

x43 means there are 43 contracts on offer?

2. As a seller, can he offer another price and contract?

3. Can he short (sell) if he have no option on hand?

These may be orders from market makers, X 43 does represent 43 contracts. Market makers are generally responsible for ensuring market liquidity.The prices they offer are generally based on the theoretical value of the option.
