for the +- 10V, as op amps have good PSRR's i would say charge pump should suffice, but the wide rail voltage will not make things easy there, most have a band of about 15V they will work in,
Both 5V rails i would say use a generic buck regulator, using an LC filter on the analog supply, and planning out your current paths to avoid noise between the 2,
Finally for the -5V, perhaps a charge pump on the 5V digital rail, when you say bias supply i do not know how stable you need it,
