Would a normal sedan automobile, not a high powered one, get better gas mileage with alloy wheels than with standard steel?

Unfourtunately most alloys wheels weigh more than steel wheels of the same size, this is because they are cast so are usually thicker. Steel wheels tend to be pressed from sheet so are thinner but as a side effect are weaker.
Of course if you go for proper motorsport alloy wheels or titanium wheels you can get lighter than steels, but they will cost you alot of money.
The lighter the wheel, the less fuel you will use, as the wheel is spinning the effect of the lighter wheel is multipled ie. you would save more taking 1kg of your wheels than 1kg off your seats say.

With the small amount of unsprung weight that you might save you would not even notice a gas savings. Better to inflate the tires to the max allowed on the sidewall of the tires for less rolling resistance.

If they are lighter than the steel wheels, yes. More horespower - no.

The lighter the better, narrower also helps fuel economy.

any reduction in unsprung weight is good weather you feel it or not , it wont give you more power but will waste less

Nope... it's all for show and resale value.
