any scent to the leaves of the first? Looks like Calamintha nepetoides
2nd is a geranium, lots of similar cultivars, don't know which one that is
3rd is a Phlomis, need to see a bit more of the plant for which species. Might be P grandiflora bit P. fruticosa is more often seen.
4 is Acanthus mollis
