The approximation will only break down if the ratio of spacing to lateral dimension is not small (that is, when the gap is "large "compared to the size of the plate) - in that case edge effects are not insignificant (but also, the usual parallel plate equation is no longer accurate). $endgroup$ –
The voltage across capacitors connected in parallel is the same for each capacitor. If you know that there is 5V across one capacitor, it means that all the other capacitors that are connected in parallel with this also have 5V across. This isn''t specific to capacitors. Any type of component in parallel will have the same voltage for all the ...
The effective ESR of the capacitors follows the parallel resistor rule. For example, if one capacitor''s ESR is 1 Ohm, putting ten in parallel makes the effective ESR of the capacitor bank ten times smaller.

If you parallel resistors you might reduce their resistance but you increase their capacitance. It may be a higher capacitance than if you just used one resistor with the combined resistance in the first place. When dealing with decoupling capacitors another factor is leakage. This paralleling capacitors increase the leakage.
Let''s arrange a few capacitors in parallel and find the resulting capacitance. The starting set consists of the following capacitors: C₁ = 30 mF, C₂ = 500 µF, C₃ = 6 mF, C₄ = 750 µF.

For low-power ICs 10nF capacitors may be sufficient and may be preferred over the 100nF because of their lower internal inductance. For this reason you also find 10nF parallel to the 100nF. In this case the smaller capacitor should be closest to the pins.
