Which one's newer computer of these two similar SONY VAIO laptops?
This one (R505): Sony Vaio R505EL 12 1 PCG 643L Laptop Computer Notebook Parts Repair Sold as Is 027242611887 | eBay
Or this one (V505): Sony Vaio PCG V505EX 12 1" 80 GB Intel Pentium M 1 5 GHz 512 MB Notebook 027242642720 | eBay

1. Which one has the better processor?
2. Is it possible to remove the ancient processor and replace it with a modern one?
3. Is it possible to plug in a 1TB HDD in these laptops (would it work?)
4. If I plugged in a 320 GB HDD with W7 already installed in it with lots of files, could it boot from it?5. What is the maximum RAM on these two laptops?
6. Could it play bluray movies?

1) Second one has a more modern processor (line was started in 2003 vs. 2001).
2) For processor upgrade you have to consider at least two things: socket and chipset. Likely, this two things will limit your choices to couple processors with pretty much the same capabilities. I won't go with this option, unless we are talking about installing 2 core processor instead 1 core, but this has to be confirmed with these particular models.
3) 1TB HDD might work, depending on how it is connected.
4) No, these laptops do not meet Win7 requirements in current configuration. By the way, you might lose activation by booting Win7 on a different hardware. Windows activation is closely tied with hardware.
5) First can have up to 512 MB of RAM max (but has 256 MB installed), and second about 2 gb max (but has 512 MB installed).
6) Both laptops equipped with DVD-ROMs. It is impossible to play Blu-ray discs in them.

Thank you. Could it play blu-ray movies if I connect a blu-ray player to it and play the CD from there?

Well, I was not able to find original hardware requirements, but according to this website both of these laptops are not ready for that task.
