first, dumps don't contain roles or tablespaces as these things are
global to the cluster, so you'll need to first create all the required
roles and tablespaces (if any) on the 'New' server.

you'll need to pre=create the new databases

     createdb db1 -O owner1
     createdb db2 -O owner2
     createdb db3 -O owner3

if your dumps were made in pg_dump -Fc  mode, then simply doing...

     pg_restore -h newhost -d db1 dumpfile1.dump
     pg_restore -h newhost -d db2 dumpfile2.dump
     pg_restore -h newhost -d db3 dumpfile3.dump

if they were made without the -Fc, eg are simple sql dumps, then try...

     psql -h newhost -d db1 -f dumpfile1.sql
     psql -h newhost -d db2 -f dumpfile2.sql
     psql -h newhost -d db3 -f dumpfile3.sql

i'm sure you can do the equivalent in pg_admin but its tedious to
describe how to point-click your way through a GUI.
