Yes, that looks right.

brown, red, brown, silver = 120 ohms
A 5 percent tolerance resistor would only have two significant digits in its stated value, so we are talking about 82000 ohms plus or minus 5%. The coloured bands would be grey (8), red (2), orange (times 1000), and gold (5%).
red 2, black 0, red 102, red 2%. 20 x 102 with 2% tol.
The color bands show the nominal resistance. The actual resistance is within some percentage (tolerance) of the nominal resistance, so the measured resistance is close to the nominal but not exactly the same. Also resistance varies with factors like temperature and age of the device.

A 1 ohm 20% tolerance resistor should not exceed 1.2 ohms actual resistance.
On a standard four band resistor: yellow, violet, black, and gold.

red 2, black 0, red 102, red 2%. 20 x 102 with 2% tol.
220 ohms with a 10 percent tolerance. Red is 2 and brown is 1. Brown is in the multiplier band so it is 10 times the value in the first two bands. Silver is in the tolerance band. Gold would have been a %5 tolerance device.
Percent
Resistors made to a 20% tolerance do not have a color in the 4th tolerance band.
not that critical
