Of the four choices, a ruler will work best.
A ruler measures length
A compass makes arcs and circles.
A vernier caliper measures the outside dimension of something
Set squares (called trianges in the US) are used to draw lines relative to a base line. Lines can be drawn parallel, perpendicular, and at the following angles with a set square. 30°, 45°, and 60°. Other angles will require a protractor or a compass.

Since depth is a measure of length, use a ruler, it's the only one that makes any sense.
Compasses measure direction or draw circles. Calipers measure small widths, not what you need here, and set squares are basically straight-edges combined with protractors.

Anything that fits down into it -- a stick, a piece of stiff wire, a ruler, a rolled up piece of paper. Then you can mark the depth and measure your device after you take it out.

What do you mean by this? What does one measure depth with? If so, a ruler, but this is a very oddly phrased question...
