If these are 1 percent tolerance resistors, which they probably are, the tolerance band will be brown. The tolerance band is the 5th band on one end of the resistor. Deductive logic: If there is a brown band on one end, and a different color band on the other end, the brown band is the tolerance band and the other band is the first number of the value.
Now, the value is a three digit number. The 4th band is a multiplier and the 5th band is the tolerance. The problem is a LOT of values start with “1” (100, 15, 150, 18, 18000, et cetera) which is a brown band. So you will have a brown band on each end. Grrrr. Keep your multimeter handy.
For example, it looks like some of your resistors in the picture are marked as follows: red-red-black-orange-brown. If these are 1 percent resistors, the brown band, per the deductive logic, is the 5th, tolerance band. The first three numbers are the three digut value: 220 (red-red-black). The 4th band is a multiplier: X1000 (orange). So these are 220 x 1000 resistors: 220,000 ohms. 220K ohms.
As some other persons said in their answers, a resistor is not a polarized device. There is no "+" or "-" orientation. You can insert a resistor into a circuit without worrying about which end of the resistor is which.
