Hi Mervyn
The second image of UK stamps contain firstly (first six stamps on top) the Definitive series of King Edward VIII issued on 01 Sep 1936. The remainder of the stamps are those of King George VI issued in 1937. This definitive issue was in use until 1947 when a new definitive issue was introduced. As far as value is concerned, they aren't worth much as they are still fairly common, maybe max ZAR40.00 for the lot on the second UK image. They are all of low denomination.
As far as the Queen Victoria stamps are concerned I will have to dig a bit deeper. There might be some value. Among them I spotted one or two "penny reds" which sell from cheap to quite expensive depending on the plate it comes from. Another thing is also always condition, which plays avery major role in terms of value.
On value I would rather you get it appraised by an expert as the stamp market is very volatile. I can put you in touch with just such a person if you require.
Will see what I can dig up on the other stamps.
Regards
Norman
