If you want to forward two ports, you may simply add another line like this:
config.vm.network :forwarded_port, guest: 8080, host: 8080
config.vm.network :forwarded_port, guest: 5432, host: 5432
A better way, in my opinion, is to setup a private network (or host-only network), so that you don’t have to forward all the ports manually.
See my post here:
Vagrant reverse port forwarding?
Additional tips
If you use the :id feature when defining :forward_port entries you need to make sure that each is unique. Otherwise they’ll clobber each other, and the last one defined will typically win out.
For example:
config.vm.network "forwarded_port", guest: 8080, host: 8080, id: 'was_appserver_http'
config.vm.network "forwarded_port", guest: 9043, host: 9043, id: 'ibm_console_http'
config.vm.network "forwarded_port", guest: 9060, host: 9060, id: 'ibm_console_https'
