Hard to decipher your English at times , but still...
1. If you have everything then building will be in the color of your kingdom/empire. If you do not have something it needs building will be gray. In this case put your mouse over something you can not build and look for red numbers. This is what you need to have to build. Put your mouse on it and a pop-up will tell what it is.
2. If you did not understand Marks - You do not spend points. You only choose where you want them to go. When get your first point in a new game a screen appears. Use circles there.
3. You need research. There are 5 (or 4, I don't remember) of them with different names. All under adventure.
4. As close as possible. If you can be closer than you need to be closer. Also can't be outside the line of your Kingdom/empire color.
5. There are ways to transform the map. I don't know them well. But I can tell that sometimes there are ways and sometimes there will be ways later (later in real life not in game).
6. My best guess - you need City level. That means more people in city. Probably even more houses so you can have more people. That, or you didn't research them.
My advise - you will need to learn that game all by yourself or you will need better English. Most of your questions are answered in game and in manual.
Your English is hard to understand Most people will not even try to understand what you are trying to say let alone use words that are easy to understand to someone with weak English.
Personally, my own patience is at an end, and I'm not that good at it myself...
