No 4 is a violet. I think the campanula is too over to tell, but if it had harebell like flowers it is almost certainly a campanula. However, there are many different sorts, blue, pink, purple, tall, short, oval leaves, long leaves???
Number 6 is an achillea or yarrow. Could even be the weed one which is white, but the leaves look better quality.
Number 5 looks like the climber, Star Jasmine or - wait for it! - Trachelospermum Jasminoides. Covered in white perfumed flowers in summer. Can be tender in winter. Mine went black 2 years ago (-17°) but recovered in early summer and grew lots of new leaves. Trim it to keep it tidy and cut off any dead bits in spring. It will wind up a support if you give it one.
