Is it possible to have both a tower and a fort in the same province(i think yes)?  If yes, then it is possible to have a tower an a city in the same province, right?

If so, how do you count the "Each players receives an amount of gold equal to the combined ratings of all provinces where he has towers or cities" during the FINAL SCORING?   (ex: Tower and citie in ZAMORA(4)= 4 gold or 8 gold)?

Thanks for the insight.

"- A player places a fort on a province he has conquered
through a military contest.
- A player places a tower on a province he has allied with
through an intrigue contest." (p. 6)

You can't intrigue or military contest a friendly province, so can't have these two in the same province. You can upgrade a fort to a city, so can't have tower + city in the same province I think.

ok, thank you, sir. I was not sure about this one.

That's correct.  You can only ever have a single type of control marker in a region.

Also, the only time you can create a city is during the age change.  Only a fort can be upgraded to a city.

Indeed you cannot control a province both in military and intrigue way. That is a nasty thing you need to consider and choose the method of expanding. When you conquer a province with the intrigue action, you cannot then conquer it by force!
