Yes
MAYBE: depends where in Ireland. Northern Ireland, yes: the same applies to Scotland and Wales, BUT if the intention is to travel to southern Ireland (also known as Eire) either directly or via Northern Ireland, than a visa may be needed, depending upon your own nationality / point of departure, as Eire is a country in its own right.
In practical terms, this technicality is frequently ignored by travellers (at their own risk, as it carries heavy penalties, particularly with the on-going concerns over terrorism etc), as the border between Northern and Southern Ireland is a land border, extremely rural, and riddles with a network of small country lanes, many of which cross the border. It would be virtually impossible, for example, to arrive in the UK, travel to Northern Ireland legitimately then on the Southern Ireland without a visa and then try to leave there for any destination other than Northern Ireland again ... and vice-versa ... it's been tried unsuccessfully way to many times!
Yes, the visa allows free travel in the entire United Kingdom (the UK) of Great Britain and Northern Ireland territory.
No. Northern Ireland is part of the UK, so the visa will cover it.

Yes South African passport holders require a visa. You cannot get an Electronic Travel Authority (ETA). You must apply in person at your nearest embassy.
If your are a European citizen you do not need a visa If you are from a visa waiver country you do not need a visa if your stay is less than 90 days If you are none of these go to the French embassy in London
The UK and Ireland operate a "common travel area" This means that legally you do not need a passport. However a passport is now the only form of identification accepted by most airlines operating between the UK and Ireland.
No, a South African citizen does not need a visa to visit Dublin or anywhere else in Ireland. If you are travelling via the UK (even in transit) I think that you now need a visa. (Not for Ireland but for the UK.) Worth checking out prior to travel just to be sure!
It depends on where you are coming from As Northern Ireland is part of the UK you will need the same Visa that you would need to enter any other part of the UK. If you are a UK citizen you do not need one
Absolutely no! You have to obtain UK visa before going to UK
