Current through one LED in series with 2.2 kΩ:

2.2 kΩ is a standard value in the E6, E12, E24 series, so it comes in almost every resistor kit.

Same first two colors, different multiplier:

What are the colors of a 2.2 kΩ resistor?

On a 4-band resistor: red, red, red, gold. On a 5-band resistor: red, red, black, brown, brown.

What is the SMD code for 2.2 kΩ?

222 on 3-digit resistors and 2201 on 4-digit (1%) resistors.

How much current flows through a 2.2 kΩ resistor at 5 V?

2.27 mA, dissipating 11.4 mW. A 1/8 W resistor is enough.

Which resistors get mixed up with 2.2 kΩ?

red, red, brown, gold is 220 Ω and red, red, orange, gold is 22 kΩ: only the third band changes, so check it carefully.
