No, a 2.2k ohm resistor and a 220 ohm resistor are not the same resistance. The "k" in 2.2k ohm stands for "kilo," which represents a multiplier of 1000. Therefore, a 2.2k ohm resistor is equivalent to 2200 ohms, while a 220 ohm resistor is simply 220 ohms. The difference in resistance values is a factor of 10 due to the kilo prefix.

56000 ohm or 56 Kilo ohm
Resistors are color coded to denote the value of the resistor as well as the multiplier. In your case a 470 ohm would be colored as Yellow Violet Brown corresponding to 4, 7 and a multiplier of 10^1.
When a resistor has a 4th color band, its color is either gold or silver, so I will assume the color bands are white-white-white-gold. The resistance is 99 GΩ ± 5%.
Green - Black - Red, but this is not a standard value. You probably want a 5.1K resistor, and that is Green, Brown, Red
You need to calculate the equivalent resistance. For instance, if the three resistors are connected in series, simply add all the resistance values up. Then, you calculate the current (in amperes) using Ohm's Law (V=IR); that is, you need to divide the voltage by the resistance.
First off, it's going to have a brown and an orange ring for the first two bands but then your last band is going to depend on the tolerance of the resistor whether it's +/- %.05 up to +/- %10.

A 0.1 ohm resistor is color coded brown (1) black(0) silver (x 10-2).
