You need to clone both, LyX layout::

Style Questions
CopyStyle   Enumeration

and LaTeX environment::

\newenvironment{questions}{\begin{enumerate}}{\end{enumerate}}

I am not sure if this works well, as enumerate is an environment, not a
command. Use the latex \newenvironment instead.

With CopyStyle, you get all the definitions of the copied style and
need to change only thing that should differ.

Describing the difference in words helps (while pics might augment
this, they cannot always replace a description, e.g. while browsing
this mail to see if I can help at all, I do not see the attachments.)

see above.

You could define 2 Styles in your layout file (one QuestionsTest, say)
and switch between them in the document.
