SHE

Must the standard hydrogen electrode(she) always be on the left side of the cell diagram?

I was confused because hydrogen on can also be reduced to H2, right? So couldnt SHE also be on the right side of the cell diagram?

The SHE just has to be the left side of the cell diagram (the anode) because it is used to determine the standard potentials of the other half reactions, which in the table is just based on reduction/oxidizing ability. The standard hydrogen electrode is just used as a reference point to measure the reduction standard potentials for the other half reactions.

Therefore, yeah I think the SHE can also be on the right side of the cell diagram, just not when trying to figure out the standards if that makes sense
