So here goes with the answers:
1) Are they numbered according to the order of places you can visit like in Undefeated?
Yes they are. However, in some places you can do things in a slightly different order, so you may find they go slightly out of sequence, depending on where you go first. An example of this would be the region of Kelagan South, where you could go to either dungeon first.
2) Are they only in dungeons or anywhere?
Two are definitely not; there is a third which I would classify as being a dungeon (because you fight enemies there) but which others might not, as it is not a 'normal' looking dungeon.
3) Can I revisit places later in the game when I've missed some?
I'm not sure from your question if this is still about secret rooms, or in general. You can revisit most places. There is one place which you can only gain access to if you have a particular quest (unlike a couple of other places where you can gain access to at least part of the dungeon without the quest). That quest must be completed before a certain point in the game, so if you miss it, that's it. Another place which you can only visit once is because of the story - and when you get there, you can see why. It is recommended that you finish all your business north of Huffon Tunnel (which is at the northern edge of the region of Kelagon South) before leaving that region to continue towards the coast, because after that you won't be able to go back through the Tunnel.
I hope that's the information you wanted, but if it's not, or if it's not clear, let me know.
