Yes. That is fine.

Yep. you simply divide the capacitance by 12 for your stings so one string
is 0.56/12 or .004666uF

Yes. You just multiply by five.
You cap sounds fine! About 20kV at 20 amps RMS should be able to take any
neon system. I use 10 caps per sting in 5 strings for my 15kV/60 (28nF)
and they have not had any problem. You should be well within the cap's
