The green one looks like Euphorbia but not sure which one. the reddish one looks like Sedum 'purple emperor'.

The euphorbia has acid green/yellow flowers in spring and a white milky sap. but it is a skin irritant so handle carefully.

welcome to GoY too :o)

Bottom one is a sedum but can't say which variety.

Definitely Euphorbia, there are a few variegated ones such as E.'Tasmanian Tiger' or 'Kestrel', and one of the purple leaved Sedums.

Many thanks to all.
