The purple one is a knautia or scabious. The bottom one is a Salvia hot lips.
The argyranthemum will probably be killed by frosts. Take cuttings now and keep on a windowsill. The scabious can be cut down and will regrow in Spring. Cut down the Salvia hotlips in Spring, down to a new shoot. If you leave it over winter , the top growth will protect the base. A mulch wouldn't hurt either.
The Thunbergia will probably be killed by frost as well. easy to grow from new seed each year.
