How to define a new font family on Beamer?
I've tried this way, but I get Undefined control sequence :
\newfontfamily\fff{xxx.ttf}
Any good idea, please?
Thanks in advance!

beamer uses the sffamily by default, so you need to define the \cyryllicfontsf using \newfontfamily:
\documentclass{beamer}
\usepackage{unicode-math}
\usepackage{polyglossia}
\setmainfont{STIX}
\newfontfamily{\cyrillicfontsf}{XITS}
\setdefaultlanguage{russian}
\begin{document}
This is a test.
Это тест
\end{document}
(I have the actual STIX fonts installed, so I haven't tested this with XITS but it should work the same.)
If you want to use a sans serif font, then Herbert's solution is the correct one. I assumed you wanted to make the default Beamer font to use XITS.
If you want to present them as examples and mark them up as such using beamer's example environment (rather than just using the generic block) you might try something like this:
\documentclass[]{beamer}
\usetheme{Madrid}
\newtheorem{examplefirst}{Example}
\newtheorem{examplesecond}{Example}
\newenvironment<>{examplefirst}[1][]{%
\setbeamercolor{block title example}{fg=white,bg=red!75!black}%
\begin{example}#2[#1]}{\end{example}}
\newenvironment<>{examplesecond}[1][]{%
\setbeamercolor{block title example}{fg=white,bg=blue!75!black}%
\begin{example}#2[#1]}{\end{example}}
\begin{document}
\begin{frame}
\begin{examplefirst}[An example of the first kind]
Something about this example of the first kind.
\end{examplefirst}
\begin{examplesecond}[An example of the second kind]
Something about this example of the second kind.
\end{examplesecond}
\begin{example}[A regular example]
Something about the regular example.
\end{example}
\end{frame}
\end{document}
which produces:
If you prefer to stick to the generic block environment perhaps something like this might work:
\documentclass[]{beamer}
\usetheme{Madrid}
\newenvironment<>{examplefirst}[1]{%
\setbeamercolor{block title}{fg=white,bg=red!75!black}%
\begin{block}#2{#1}}{\end{block}}
\newenvironment<>{examplesecond}[1]{%
\setbeamercolor{block title}{fg=white,bg=blue!75!black}%
\begin{block}#2{#1}}{\end{block}}
\begin{document}
\begin{frame}
\begin{examplefirst}{An example of the first kind}
Something about this example of the first kind.
\end{examplefirst}
\begin{examplesecond}{An example of the second kind}
Something about this example of the second kind.
\end{examplesecond}
\begin{block}{A regular block}
Something in the regular block format.
\end{block}
\end{frame}
\end{document}

xelatexorlualatex. Then it is easier, for example:
