Is there a command which does the same like \clearpage (typesetting all floats which have not been typeset yet) but then does not insert a pagebreak but continues with the following text/graphics on the same page?

As switching between twocolumn and onecolumn causes a page break, one may use the multicol package and its multicols environment instead. (The environment's optional argument is used for introductory one-column material.) In the following example, I use the twocolumn class option to achieve smaller margins, then temporarily switch two \onecolumn at the start of the document. Page breaks before chapters are removed by disabling \clearpage inside a group.
Note: The vertical space before chapter 1 (typeset with multicols) is actually larger than the space before chapter 3 (typeset with \twocolumn). The larger space is caused by LaTeX bug 3126 (\twocolumn interfering with \topskip); for consistent spacing, use multicols environments for every chapter of your document. EDIT: Even better, use Frank Mittelbachs answer to Is it possible to define a `multicols{2}` preamble switch that works for \chapter?
\documentclass[twocolumn]{book}
\usepackage{multicol}
\setlength{\columnsep}{20pt}
\newcommand*{\sometext}{Hello, here is some text without a meaning. This
text should show, how a printed text will look like at this place.
If you read this text, you will get no information.}
\begin{document}
\onecolumn
\begingroup
\let\clearpage\relax
\begin{multicols}{2}[%
\chapter{First (and some text to fill the line)}%
]
\sometext
\end{multicols}
\begin{multicols}{2}[%
\chapter{Second (and some text to fill the line)}%
]
\sometext
\end{multicols}
\endgroup
\twocolumn
\chapter{Third (and some text to fill the line)}
\sometext
\chapter{Fourth (and some text to fill the line)}
\sometext
\end{document}
The problem seems quite abstract, because it's quite rare to have an index start without a page break. However, here is a possibility. Since you don't want page breaks, it's necessary to avoid any automatism in index generation.
\documentclass[a4paper,twoside,11pt]{book}
\usepackage[noautomatic,nonewpage]{imakeidx}
\usepackage{hyperref}
% declare new index files
\makeindex[name=names,title=Name Index,intoc]
\makeindex[name=titles,title=Title Index,intoc]
\indexsetup{level=\section*} % no page break with sections
\begin{document}
\tableofcontents
% generate fake index entries
\count255=0
\loop\ifnum\count255<200
\index[names]{Surname\number\count255, Name\number\count255}
\index[titles]{Title of Work\number\count255}
\advance\count255 1
\repeat
\clearpage
\phantomsection
\section*{Test 1}
\addcontentsline{toc}{section}{Test 1}
\printindex[names]
\printindex[titles]
\end{document}

Yes, and this is discussed as one of the advantages of the
afterpagepackage. UseThis will flush all processed floats after the current page has been completely set, technically avoiding a visible
\clearpage. See the first use-case in theafterpagedocumentation (page 1):
