Hostile mobs spawning rules on PS4?
I found a skeleton monster spawner and build a xp trap around it. It's the typical trap described in all the YouTube videos:

The trap works and I wanted to extend it, so that also other hostile mobs get caught. Therefore I added two more rooms that look exactly like this one but without water (because I read something about hostile mobs can't spawn - besides by a monster spawner - on flowing water? Is that true?).
Rooms:
- completely dark
- all cobblestone
- 9x9x3 (LxWxH, at some points even a height of 4 blocks)
- tested with and without water
Problem: Other mobs (but skeletons from the mob spawner) don't spawn. Neither in the two new rooms nor in the first one.
I already tried to go more than 24 blocks away, wait some time and then come back to check the rooms but they were still empty!
I checked during day and night.
Questions:
- Can other hostile mobs spawn near mob spawners in general?
- Can hostile mobs spawn on floating water?

Spawning rules on Bedrock edition are the same for the most part.
For your case relevant are the following rules:
Hostile overworld mobs do not spawn when:
- The Block checked for spawning is an air block (unless spawned by a spawner)
- there is no space for the hitbox of a mob
- there block height is not a full block (e.g. carpet, snowlayers, slabs)
- light level is >=7
- water or lava on the block (either source block or flowing)
