Looks like you have some aloe there.

FataMorgana

Don't know what the middle one is but agree, the two on either end look like aloe vera to me.

Yes, the one on the left and the one on the right look like aloes, probably Aloe vera (a closer, clearer photo would help). And there are some behind the one on the right, which may be attached to it (its "pups").

I don't know the plant in-between the aloes.

Thanks a lot guys, much appreciated

Looking again at the middle one it may be another marigold (tagetes).
