Identification: Neoregelia?

Does anyone know the names of these variegated plants. Are they Neuregelia? Do you know the name of the varieties?

 

they look like Clivias mayb ??.. google that . or hopefully someone else will chime in here ..

One of them (at least) looks like it could be Neoregelia 'Myerdorfii', as seen at this link:

It may be tough to pin down an ID on these Bromeliads. Another possibility is Neoregelia fireball variegata & another still is Neoregelia 'Martin'.

 

Thank you very much. I had no idea that there were so many choices.
