01. Where is the correct placement to put ammo? enemies?
when designing your levels, use reference pictures, and make the levels around them loosely. remember to add lots of detail.
02. How big the rooms should be, how many enemies should be an one area
room size depends on what will happen in said room, and try not to have any more than 3-4 enemies to engage the player.
03. How many enemies should spawn kind of deal.
like I said, 3 or 4. to keep your fights long, try giving them 2 lives. that makes them take longer to kill.
