The \begin{lemma} like all the other section stuff from
`reftex-section-levels' and `reftex-label-alist' is only found if it is
followed by "[[{ \t\r\n]" (regexp-wise).  I have to check if this
restriction can be loosened.

The first \begin{lemma} is found and since it is treated as a section,
the bound for looking backwards during parsing is set to the point right
after it (in `reftex-parse-from-file').  Now when the label after it is
found, it is not searched beyond this bound and the type of environment
cannot be determined correctly.  If you look at the .rel file you will
see that the type key for the first lemma is "s".

Nothing, those are bugs.  As a workaround you could put the labels in a
separate line and use " " as type key when calling `C-c )'.  I'll need
to check more closely how the bugs can be fixed.
