pull up resistor

[Orange]

I've got some instructions that tell me to connect 470 ohm pull up
resistor to pin number 43 of chip.
Is that OK? (I've heard that pull up resistors are usually 10Kohms or
47 Kohms)

The resistor should be connected between pin 43 and +5V , or am I
wrong?

It depends on what the purpose of the pullup is. If it is to provide
current for an output that is driving a significant load, 470 ohms
could indeed be correct.

If it's just to hold an input high, then the value doesn't matter much
but is generally 5K or 10K.
