Strange Alliums

We were given these garlic bulbs by a friend whose father had kept them growing for decades.
One bulb looks like garlic, the other three look more like a form of shallot, or elephant garlic.
Does anybody recognise them? Whatever type of allium, we’re planting them in pots to get them started before planting on in the allotment, then giving some back, which was the reason they were originally shared.
