Whom among the Sahaba led prayers during the lifetime of the Messenger of Allah (peace be upon him)

During the lifetime of the Messenger of Allah () there have already been a lot of mosques and situations where some Sahaba () had to lead the prayers in congregation in the Masjid an-Nabawi in Medina during his absence etc.. And other Sahaba () have been leading prayers in mosques elsewhere too! I would like to have a list of those Sahaba with references. If you could also describe the situation or circumstances for those prayers which were led in the Masjid an-Nabawi that would be great! I'm sure that I read some ahadith saying that at least abu Bakr and (if I remember well) Ubay ibn Ka'ab () are known to have lead some prayers in congregation!
