What does all this mean with "Fill next turn" and don't let your city reach population limit.
I don't understand what you are taking about here.

And what does the extra food in your granary box mean?
You mean if your city has a granary? the food box is cut in half, the upper half will function as the old food box, only half the size. The lower half is the actual granary, it will empty if you city is starving, giving you a small extra buffer before its pop is reduced.

What if there is no more room to expand, what should I do then?
Depends on what you want. Though the usual thing to do is to
make room. (read: conquer land from the other civ)
If you are talking about city growth: usually you'd let your city sit at its growth cap while maximizing production.
if you want to maximize science, (at the cost of production) you could opt to build hospitals (in your core and semi-core) and irrigate all the land, then let your cities grow as much as food allows. The citizens that can't work the land will be specialist.

And when should I start building military?
This is difficult. At the early part of the game, you want to build some regular warriors in-between settlers and workers.
You should start at your
serious military somewhere before the point where all the free land it taken. Ideally so that you can switch to expansion by conquest almost right after you found the last city on free land.
You'll have to develop an eye for it, to see this point coming.

And how many should i make?
For war, you should just devote all core and semi core towns to building vet units non stop, except for your settlers pumps, and those should eventually start on units too, because at some point settler production should go to the hopelessly corrupt outer towns.
Do not stop building units until the war is over. (focus on your goal)
If you want to be a peaceful builder, the question is going to be more difficult. There are at least 2 things I can tell you you should NOT do:
Do not build an X number of units per city, instead, only build enough units to defend your borders, if you have a huge empire but you are on your own continent all alone, you can do with a very small army.
Do not build defensive units, instead build horseman/knights/cavalry and tanks/modern armor. (mix with artillery later on)
