I'm almost finished the civics. I miss some details:
1. <bNoUnhealthyPopulation> means no

caused by population?
Not no

from popultion, no

from population. Normally you get 1

per point of population.
2. <iExpInBorder> What does it means?
I think you mean iExpInBorderModifier. It is a percentage modifier for the amount of experience a unit gains from a combat within your borders. If you set it to 50, each time one of your units gets XP in your borders it should get 50% more (rounded down, so it would often have no actual effect).
3. <bBuildingOnlyHealthy> means no

caused by buildings?
Again, it is

, not

. If a building gives health, it still would give it. But if a building gives unhealthiness it no longer does if you are using a civic with this set.
4. <iStateReligionUnitProductionModifier> is likes <iStateReligionBuildingProductionModifier> but one for units and one for buildings?
Yes.
5. <Hurry/> I don't understand what Does it signified and what can we write :

,

,

,

,

,

, or

.
It is either HURRY_POPULATION (you can rush via sacrificing population, like the Slavery civic) or HURRY_GOLD (you can rush with money).
