Usando o seguinte código da resposta paraessa questão

Gostaria de posicionar as caixas verdes no local do nó B. Eu usei o código

    \foreach \i in {0,...,3}
\node at ([shift={(90:5.4cm)}]B.center) (n\i) [boxc=green!60!white] {};

Mas isso não funcionou. Como isso pode ser feito?

Não consegui descobrir como posicioná-los corretamente. Tive que fazer isso manualmente, como fiz com as caixas violetas em outra foto do tikz.

Acabei de perceber o seu problema... Seu problema é que você definiu esse estilo com a opção on chain... removi isso em um terceiro mesmo estilo nomeado boxde aqui está o resultado:

\documentclass{article}
\usepackage{verbatim}
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage{pgfplots}
\pgfplotsset{compat=1.15}
\usetikzlibrary{positioning, chains}

             inner sep=0pt, outer sep=0.96mm,
             on chain},
   boxb/.style = {draw, thick, fill=#1,
             minimum width=6mm, minimum height=7.1mm,
             inner sep=0pt, outer sep=0.96mm,

   boxd/.style = {draw, thick, fill=#1,
