First, create an enum to store your faction data.

Example:

pawn Code:

#define MAX_FACTIONS 10

new FactionCount;

enum Factions
{
Name[32], //String, that's why [32] = length
Skin, //Integer
Weapons[5][2], //5 for example, use more if you need, [2] = ammo and weapon id
Float:PositionX,
Float:PositionY,
Float:PositionZ,
};

new Faction[MAX_FACTIONS][Factions];

Then you could create a function to create a faction (Easier for you if you create them from your gamemode)

pawn Code:

stock CreateFaction(name[], skin, Float:x, Float:y,Float:z)
{
FactionCount++;
new id = FactionCount;
Faction[id][Name] = name;
Faction[id][Skin] = skin;
Faction[id][PositionX] = x;
Faction[id][PositionY] = y;
Faction[id][PositionZ] = z;
printf("Faction created: %s", name);
//I let you configure the other things like weapons if you need them
}

Then under OnGameModeInit; create your factions:

pawn Code:

public OnGameModeInit()
{
CreateFaction("Example name", skinid, x,y,z);
CreateFaction("Example name 2", skinid, x,y,z);
return 1;
}

Hope you got my point
