[SOLVED]Is it possible to install multiple gcc toolchains with pacman?

For some reasons, I need to compile different software with different gcc toolchains, some are really old.
I have tried downgrade, but sadly, for most old package like gcc 8.3，I got errors as this:

error: '/var/cache/pacman/pkg/gcc-8.3.0-1-x86_64.pkg.tar.xz': invalid or corrupted package (PGP signature)

The oldest version I could take is about 10.1，does it mean I can't install older gcc toolchains with pacman?

Do not downgrade these packages.  Previous versions are in the AUR and can be installed along-side the current version.

Many thanks. I know with apt-get I could select muliple gcc toolchains with apt-get install gcc7 as so on. But I can't find a way to go with pacman.
