Which supply source changes the polarity constantly?

AC source of electric power changes changes polarity constantly, in amplitude.

When switch is off of power supply output shown on the multimeter is negative voltage from power supply?

Yes.

Which voltages are supported by a Toshiba power supply?

The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and packaging will state voltage recommended for the product.

How do you make power supply variable?

A variable power supply is one whose output voltage (or current) can be adjusted and therefore set to a desired figure. They are used in development and design odf circuits, eliminating the need for possibly many power supplies of different output voltages. Once a circuit is connected to it, the output would not normally be changed.

Which filter do you use to remove pulsations from a power supply output?

There is no answer to this. If a power supply pulsates, what frequency, etc. If a power output needs filtering there are oodles of ways to do it depending on the desired result and the starting conditions. A starting point is a big capacitor.
