Answer 1

The code in the linked question and answer contains the line

\renewcommand*{\intitlepunct}{\space}

As you can see in the following reduced MWE

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[style=authoryear, backend=biber]{biblatex}

\renewcommand*{\intitlepunct}{\space}

\addbibresource{biblatex-examples.bib}

\begin{document}
\cite{sigfridsson,pines}
\printbibliography
\end{document}

this causes the "in" to be followed only by a space and not by a colon.

Simply remove that line and you will get back the preset value of \addcolon\space, which gives you a colon.
