Cholecalciferol can be derived from sheep's wool, so those are not vegan, are they?

They do contain cholecalciferol, so no not vegan if that is derived from sheep's wool.

Are theses suitable for vegans

No they are not. Synthetic cholecalciferol can only be made from sheep's wool. The packaging has been changed to reflect that these are not vegan.

Can anyone tell me if the cholecalciferol is derived from algae, please?

No, I think its derived from lanolin

How many micrograms of vitamin D is there in each tablet?

You would normally divide the "units" figure by about 50 to arrive at the figure for micrograms. Thus 4000 units is about 80 micrograms of vitamin D per tablet. This is only a rough estimate. Micrograms are abbreviated to µg, not mg. I read that the normal daily dose for adults is about 800 units. The safe upper limit is about 10,000 units per day. These tablets thus seem to be for a high but safe dose.
