My bad. I meant 4.7kΩ

My question is really whether I can twist all the resistors together after soldering them to the pins to get them into pins 1 and 8?

Pins 26,27,28,30 and 32 through individual 4.7Ω resistors to pin 8

Then insert 6502 and check pin 9.

Have I got that right?

if so, how should I connect 5 individual resistors to pin 8? Just twist their ends together and insert 1 of the resistors to pin 8?

Unless you've made some typos, I think they recommended 4k7 = 4.7kΩ resistors rather than 4.7Ω (which wouldn't really serve much purpose being that low).
Although this may not make too much difference, if just going to supply / ground and there's nothing driving to drive out from pins you're trying to pull up / down.
