I have a lot of chapters and sections inside chapters tex file. I want to make a separate folder for chapter and there put separate sections tex files. How I should do this? I am using report for now, so I am just \include all chapters files in maintex. I am thinking of changing everything to book, but I don't know will it look the same? Or maybe I could stay with report?

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}
Here' a possible solution using the titlesec package to add the color to the chapter headings; the color for the part headings (and their ToC entries) was added through a redefinition of the internal macros \part, \@part and \@spart; the color for the chapter entries in the ToC was achieved by redefining \@chapter. The color schema was implemente through a simple \ifcase:

\usepackage[tbtags]{amsmath}
\usepackage{xcolor}

Just as a personal comment, this coloring schema has to be handled very carefully (selecting the appropriate colors is crucial) in order not to become distracting and to avoid achieving an unpleasant layout.
