Okay, here are the floors of one slice of one fifth of the 5-bastion fort, from top to bottom, think of it as if it was a pizza:

LEGEND:
White with straight black lines in a crossing pattern (XXX) -> something solid, usually stone, bricks or ashlar. It means there's a wall there.
White circles over black or black circumferences over white -> there's nothing there, there's void, open air, whatever you went to call it.
White with straight black parallel lines with dots -> compacted earth.
Gray -> there's either a flat surface or a slightly inclined surface.

Reference points: Every floor map has 4 corners that are at the same position (horizontally speaking) as on the other maps

Top surfaces (parapet/breastwork so not exactly a floor):

Parapeto-5p-bastion.png

Top floor, walkway, where you can begin to install cannons, at the fronts of the bastion and at the flanks.

Intermediate surfaces in the form of a ramp to access the bastion, slopes behind the curtains to give them stability and another parapet for the orillon gun emplacement.

Main floor, the parade ground or barracks square, where the facilities usually are. Here there are usually some buildings to serve as barracks, the main powder keg, the church, the mess hall, etc. Also, there are a pair of tunnels that lead to the gun emplacements that can be made behind the orillons. At those gun emplacements, there's also a mini-powder keg for every gun in the bastion, in cupboards in the wall and a stash of cannon balls.

Glacis. An artificial ramp made of compacted earth that covers the foundations of the fort from enemy cannonfire Its higher edge (the one closest to the fort) is about 1.7 meters above the level of the main floor. the lower edge is about 0.5 meters below the level of the main floor.

Camino de ronda (Parapet walk according to Google Translate). It's an advanced ditch, about 1.8 meters below the higher edge of the glacis. From where you can easily defend the glacis with muskets if there's not enough space at the walkway.

Moat, ditch. Deep hole that separates the fort from the glacis and the parapet walk. It's covered by the guns behind the orillons and the guns at the flanks of the bastion.

Finally, if you put all the maps at their appropiate heights, eliminate the "void" textures and you take a step back, you may see the form of the bastion:
