Whilst those are lovely photos they are not close enough to be able to see if you have wind damage, or whether they need to be repotted into large pots and planted in the ground. Could you take a close up on the leaves and add it to your question please.

The larger two look to be just about at the limit for the pots they are in, but they shouldn't be showing signs of stress from that, yet. I see, however, that they appear to be in a very open, exposed spot, and may be suffering from too much sun, especially in the drought earlier this summer.

Yes it does look as it they get full sun all day.
