Calathea plants...help me identify these please

[Kovi]

Hey guys so one of the local nurseries has a bunch of calathea species for sale that I'd like to get but the problem is identifying these species. Can you guys please help me identify these following species please. Please note:

The lady at the nursery said that due to it being winter that alot of the calathea have kinda faded in colour.
