How long does Pluto take to go through the zodiac?

About 248 years (90,560 days) for one full circuit as seen from Earth. That is the synodic figure this site computes ephemeris positions against, not a sidereal orbital period, and it is what determines how long Pluto stays in one sign: roughly one twelfth of the cycle, stretched or compressed by retrograde motion and by the eccentricity of the orbit.

Which sign does Pluto rule?

Pluto rules Scorpio. Rulership is a fixed correspondence, so it holds in every chart; what changes chart to chart is whether Pluto actually occupies one of those signs.

Is Pluto a personal planet?

Pluto is classified here as a transpersonal. Transpersonal planets stay in one sign for years, so the placement is shared by an entire generation and says little about an individual on its own.

How often is Pluto retrograde?

Pluto turns retrograde roughly every 366 days. Retrograde motion is apparent, not real: the planet keeps moving forward, but seen from a moving Earth its longitude decreases for a stretch. Because the effect depends on the geometry between two orbits, the interval and the duration both vary between cycles, so a stated average will not match any single retrograde exactly. Live station dates are computed rather than tabulated on this site.

Hellenistic tradition

Pluto was discovered in 1930 (reclassified as dwarf planet 2006) and is not part of classical Hellenistic tradition.

Modern Western reading

Modern Western astrology assigns Pluto rulership of Scorpio. Read as deep change and underlying power.
