Is there a specific order we have to follow when drawing cell diagrams other than anodes on the left and cathodes on the right side?

Another order is to have solids on the outsides of the diagrams while having gases and liquids on the inside of the diagrams. Don't forget to use a comma when there are molecules of the same phase.

Other than that convention,
1. Put the inert electrodes on the far left and/or far right. (e.g. Pt(s))
2. Generally, the molecules are put in order of reactants to products on either side of the salt bridge, but I don't think this is a strict rule.
*If there's more than one reactant/product, it doesn't matter in what order you put them in.

In the cell diagram, for the cathode, the product with the more electrons should be written last. For instance, Ag+ l Ag. The vice versa applies for the anode. Therefore, you always need to compare the products and reactants of the half-reactions to make sure you get the order of products and reactants right in the cell diagram.
