One could directly define the variables as σ1, ..., σ5.

Note that in IPython (and in Jupyter), typing \sigma followed by the TAB key displays σ.

Here is a more old-fashioned way to get something like in the question.

sage: s = dict((i, SR.var(f's_{i}', latex_name=fr'\sigma_{{{i}}}')) for i in (1 .. 5))

sage: s[1] / s[2]
s_1/s_2

sage: show(s[1] / s[2])


$$\frac{\sigma_1}{\sigma_2}$$
