Adding memory to an iMac 27 (late 2009)

Can I insert two OWC brand 2.0 GB chips in the two empty slots, keeping the original existing Apple chips in place -- thereby mixing two different brands -- without any problems ?

[The online compatible upgrade is: OWC PC3-8500 DDR3 1066MHz 2GB]

iMac, macOS 10.13

Is it possible to use RAM memory chips from an old MacBook Pro in an old iMac? I have two old Macs and want to know if I can take the memory chips out of one of them and insert them into the other. Here's the setup of the two machines: 13-inch MacBook Pro mid-2010 — 2.4GHz Intel Core Duo, OSX 10.10.5 — 4GB (2 x 2GB) 1067 MHz DDR3 memory. (Screen + hinge broken, battery swollen, trackpad broken, destined for recycling.) 20-inch Polycarbonate iMac 2006 — 2GHz Intel Core Duo, OSX 10.6.8 — 2GB (2 x 1GB) 667 MH SDRAM memory. Question: Is it possible to take the two 2GB 1067 MHz DDR3 memory chips out of the broken MacBook Pro and then use them to upgrade the iMac, by swapping them out for the iMac's existing 1GB 667 MH SDRAM chips? Or is that fundamentally impossible for some reason (e.g. the memory slots are different sizes in the two machines, or 2006 iMacs can't use1067 MHz DDR3 chips, or other technical limitations)?

Can I reuse the RAM from my late 2013 27 inch iMac with a new 2022 iMac to increase the memory? I wonder if anyone can advise me? I have an iMac late 2013 27 inch and with all the Zoom lessons I have to teach these days my computer often crashes or struggles. I upgraded the RAM to 24RAM successfully and am considering adding 8RAM to make it the maximum of 32 RAM in the hope of even more smooth work. However that will mean wasting some of the RAM cards which I would need to remove. If I did buy a new 2022 iMac could I use the old RAM cards from my old computer or are they too outdated? If I bought a new computer with 64 RAM, would there be enough slots left for me to add my old RAM cards if they were compatible? Very long question/ questions but would appreciate your expert advice.
