When modelling plate elements, should the individual elements satisfy any minimum requirements for the ratio of the length of their side to their thickness?

No, they do not have to. However, for the overall slab or wall, if the span in either direction is less than 10 times its thickness, then the slab or wall becomes more like a solid than like a plate; and thick plate theory may not be adequate. In that case, 8-noded solid elements may be necessary.
