what software upgrade for my laptop ?

good evening
I have an 8 years old mac laptop and I have 3 OS discs from my desktop mac pro
tiger , leopard and snow leopard CDs
Can I upgrade my laptop with one of these OS discs ?
my old laptop is a powerbook g4 17" ,powerbook 5,7 , CPU type PowerPC G4 (1.2)
CPU speed 1.67 Ghz , memory 1 GB , Boot ROM version 4.9 1f1
Thanks

None of those disks can be used as they are for the Mac Pro. Also, your Powerbook can only be updated to Leopard as Snow Leopard is Intel only.

And Leopard full retail install DVDs are selling for well over $100.00.

When I bought the software the apple guy told me that I can install the OS disc into 5 different computers

What do you mean Snow Leopard is Intel only ? is my laptop an AMD processor ? I cannot read what processor brand I have

Unfortunately, you cannot use any of those discs if they are gray. If they are retail discs, you can use the Leopard disc to upgrade your PowerBook.

Buy another GB of RAM if you can upgrade to Leopard.

Your PowerBook is a PowerPC computer, not Intel hence newer software will not install. As advised OS X.5 Leopard is as far as you can go and then you will need the black full retail install DVD, not a silver/grey disc which as also advised are model specific.

Thank you for all the good advices , yes my Leopard is the black full retail install DVD, but now I don't know if I can tinker and open it up to add more RAM ,I might break it.
Please explain me what is the difference between PowerBook, PowerPC and Intel. ???
I thought Intel was only the competition to AMD.

You won't break anything. It can't be any easier:

Your Mac is a PowerBook. It has a PowerPC processor in it. Intel processors were introduced after the PowerPC.
