Cooling and heater hoses with metal ends rusted out can I put all rubber hoses

I was thinking of using copper pipe I have to take them apart to see what size all the hoses are clogged with rust at every bend THANKS PUSHROD

Copper pipe will work just fine! .. Those 'new hose assemblies' are fairly expensive and can be a real B ear to install, especially on that engine.. Had a 04 Ranger with the DOHC 4 cyl that had a hearer hose 'assembly' that wrapped all the way round the engine... Well the plastic Y pipe , that is an integral part of the assembly, broke off at the rubber hoses, I just made another Y pipe from metal piping and brazed it together and fixed that problem, saved about 3 - 4 hrs of work and the customer a bunch of money... It's still going strong! .. Now I do this stuff for a living but you can do it, just got to get in the right frame of mind!... Again, Good luck with it!
