As I look at this, it seems to me that your first two work just right.  The
TAB I get is right for them - 0000 for the first chord, 0003 for the second
chord.

For the third chord, I think you have the wrong notes.  If the open 3rd
string is a d, then the second fret third string should be an e, but you
coded it as a c.  Similarly, if the open second string is an fis, the 1st
fret second string should be a g, but you have it coded as an e.  And if the
open first string is a b, the second fret first string should be a cis.

Also, you have to watch out for the relative notes.

If you code the third chord as

<a\4 e'\3 g\2 c,\1>

everything works out just fine.

Also, since you are setting the global string-count to 4, there is no need
to include a w:4 in your fret diagram definitions.

This is the revised code I tested.

   \new TabStaff \relative c'' {
      \set TabStaff.stringTunings = #'(11 18 14 9)
      \set TabStaff.highStringOne = ##f
      \textLengthOn
      % Set global properties of fret diagram
       \override TextScript #'fret-diagram-details
      #'finger-code = #'in-dot
      \override TextScript #'fret-diagram-details
      #'string-count = #'4
      {<a\4 d\3 fis\2 b,\1> ^\markup \fret-diagram
#"d:0.35;4-o;3-o;2-o;1-o;"}
      {<a\4 d\3 fis\2 d\1>  ^\markup \fret-diagram #"d:0.35;1-3-3;"}
      {<a\4 e'\3 g\2 cis,\1>    ^\markup \fret-diagram
#"d:0.35;4-o;3-2-2;2-1-1;1-2-3;"}
}

I think it works correctly.

HTH,
