Anything less than CoreDuo (meaning PowerPC CPUs) can only handle Leopard.
Snow Leopard needs Intel processor. SL also needs 1 GB RAM, but put in as much as you can.
Lion needs Core2Duo or better. Lion needs 2 GB RAM, but put in as much as you can anyway.
Start with "how high can you go?".

I wanted to install CS 5 designers edition and my OS X 10.4 didn't support it. So I was wondering which OS X version will support CS 5. If I add 2 GB memory in my iMac will that help to install the Lion?

Not sure about CS 5. Still need to figure out the memory situation.
If you have the Core2Duo, you can run Lion, but 2 GB RAM is bar minimum for functioning Lion, from all reports. You should max out memory.

That designation indicates the max memory you can run. Report your model and processor info but NOT the unit serial number.
