I'd imagine SN15 will be analysed and possibly retired with some parts re-used - engines. That said they could run it again to fly some more sub-orbital tests. Possibly after SN16 as they'd need to add things/make changes.
12,13,14 were all removed from testing or dismantled if they'd been constructed already as they'd already jumped further ahead than expected with earlier testing.
I think the Orbital prototypes start at SN20.
Not sure what number is the switch from 4mm stainless to 3mm stainless for reduced vehicle weight and increased payload capacity.
