Sarr 1 is some kind of purpurea (purpurea ssp venosa or purpurea ssp purpurea most likely), but you can't tell from that photo. If the flower it makes has a red or red/green belly, it's purpurea ssp purpurea. If the belly of the flower is yellow or off-white, it's an ssp venosa, or possibly ssp venosa var. burkii (see Sarr 5 for more epic confusion).
Sarr 2 I'm fairly sure is rubra x psittacina (S. x gilpinii). If not, there's definitely psittacina in there somewhere.
Sarr 3 is an x catesbaei (= purpurea x flava natural hybrid - here's a pic of mine:

Sarr 4 isn't a scarlet belle; but it does look like a psittacina x rubra ssp. wheryi. It could be an S. courtii (= purpurea x psittacina) that hasn't gotten enough light. If it turns completely red under full sun, it's courtii. If it doesn't and the color stays more true to its current coloring in the pic you posted, it's S. psittacina x rubra ssp. wheryi.
Sarr 5 looks most like purpurea ssp venosa to me, but it could be a rosea (synonym for purpurea ssp venosa var. burkii). If the pitchers never get about this fat (
