Hello!
Yes, exactly. All capacitors must be connected to the area marked in yellow. Scratch some solder mask from the part of yellow area, where the copper is present.

By the way, the capacitors A, B, C, D, E, F must be replaced, because they are corroded.
A= PC1809 - 4.7µF/25V, package 0603
B= PC1810 - 4.7µF/25V, package 0603
C= PC1811 - 4.7µF/25V, package 0603
D= PC1806 - 2.2nF/50V, package 0402
E= PC2053 - 100pF/50V, package 0402
F= PC1807 - 100nF/25V, package 0402

If there are no corrosion on the remaining of the copper and the solder mask does not resign from the copper, then there is no fear of corrosion progressing.
However it's best to protect such area of missing copper with a UV curable solder mask.

If we are talking about a filter capacitors (as in the picture from your first post), it's always best to replace them with their original values, otherwise the resonance may occur between multiple used capacitors which defeats their purpose.
