would i be able to just define 0.6 if i want AI to spawn on Skalisty island even though its outside the grid on the map provided (Chernarus) and is it possible to add 1 class more (1. leader 2. sniper 3. rifelmen 4.Anti Air)?
Use a static spawn, just define the area that you want and spawn them there. A 4th class is not possible. Anyhow, what would you give AA as weapons ? A stinger? If you use rmod2 you might even be able to do that, but with the reammo function you will have a deadly AA that nobody will be able to pass.
