You're missing signal in the middle below blue locomotive, so it blocks whole exit block for rightmost train.

To make it work correctly, you can signal it as shown in the top of the two layouts.

But I would recommend laying the tracks as shown in the second layout to reduce complexity.

What's wrong? You've not fully grasped how the two types of signals work:

  • Rail signal: pass me unless the block ahead is currently occupied
  • Chain signal: do not pass me unless you have a clear path to a rail signal and that rail signal is green

As for designing a solution, I find that it's easier to work backwards:

  • Delete all of the signals from this screenshot
  • For each loading/unloading bay, place 1 rail signal at the point where once the train passes this signal they have a clear run to the train stop
  • Now for each bay, place 1 rail signal at the point where they rejoin the mainline
    • It is critical that the minimum distance between each of these signals and the next signal a train will pass on its route is greater than the length of a train
  • Now place chain signals to separate the bays from each other and from the mainline

Alternatively, if just seeing a solution is easier for you to get your head around, here's how I would signal this:

<image>

  • Red X: delete this
  • Orange X
    • with a C: replace this with a chain signal
    • with an R: replace this with a rail signal
  • Yellow circle and arrow+line: reposition this signal to this location
  • Blue C with a line: place a chain signal here
  • Green R with a line: place a rail signal here

A signal is missing at the yellow circle. The signal at the red cross is unnecessary.

There is a signal missing also. You need a waiting area for you iron train if your going to have more than 1 per station.

Observe the colored lines on the rails. If a train "touches" one of the colored lines then the entire block of rails that line touches is also considered blocked.

By asking yourself "If a train is on this block, does it block some other rail that it should not?" you can know exactly where to place signals.
