For omicron, if you are using LaTeX’s default Computer Modern font then enter omicron just as ‘o’ or ‘O’. If you like having the name or if your font shows a difference then you can use something like \newcommand\omicron{o}. The package unicode-math has \upomicron for upright omicron and \mitomicron for math italic.

While the set membership relation symbol ∈ generated by \in is related to epsilon, it is never used for a variable.
