I am using \longtable command in a thesis preamble. My problem is that my data are large numbers, and I need to reduce the size of the table to footnote size. I tried using \begin{footnotesize}–\end{footnotesize} commands, it gave me an error message. What is the right way to reduce the size of the table with using a longtable?

I've cut your code down a bit for demonstration purposes, to make it a bit more minimal. But one way to do this is to specify the font size for each entry through the setup of the longtabu environment. For example:
\documentclass{report}
\usepackage{tabu}
\usepackage{longtable}
\usepackage{booktabs}
\begin{document}
Composition of samples
\begin{longtabu} to \linewidth{>{\footnotesize}X[l3.0] *{5}{>{\footnotesize}X[c]}}
\caption{Composition of samples} \\
\toprule
\textbf{Component} & \textbf{Text1} & \textbf{Text2} & \textbf{Text3} & \textbf{Text4} & \textbf{Text5} \\
\midrule
H$_2$ & 3.94 & 3.81 & 4.03 & 3.88 & 4.01 \\
\bottomrule
\end{longtabu}
\end{document}
Because the declaration \footnotesize affects only the relevant column, it does not affect the caption. However, you do need to specify it for each column. If you have several consecutive columns with the same definition, however, you can combine those using the *{<number>}{<column specification>} syntax as I've done for 5 of the 6 columns in this case.
This produces:
You can not nest longtable: just use longtable for the outer table, and tabular for the inner ones.
