I'm just curious to know if a b16 crank is interchangeable with a b18c crank. I.E., will a b18c crank fit in a b16, or will a b16 crank fit in a b18c?

Yes

and according to c-speedracing's compression calculator, it considerably bumps your compression with the b18c crank in the b16, but with the b16 crank in the b18c it will drop it down pretty low

how did you use the c-speed calc to figure out compression/displacement???
what were the options that you put in? that calc. doesn't give you the option of selecting the crank.
also, what would the stroke be with a B18C1 crank in a B16A2 block using B16A2 pistons and rods ???

Well, given that the B16's pistons are only .5mm "in the hole" (0.020 inches), pushing the piston up 5mm at the top of the stroke with the GSR crank and the B16 rods- you would probably end up slamming into the top of the combustion chamber. You'd want to run custom rods with that setup- like 130mm or something... which would bring your rod/stroke ratio down to 1.49. Definitely not good for revving like the B16 does stock.

wait a sec, doesn't a longer r/s ratio give you longer dwell at TDC and BDC and increase piston speed.
