(1) Basically any synchronous buck which can be forced to operate in CCM or in forced PWM and for which a negative current limit is large enough and specified can work in low-power, fly-buck configuration. Select the appropriate device version out of a device family. Cross-check negative current limit and loop stability - see data sheets and additional collateral.
(2) Basically any buck converter, even non-synchronous buck. Cross-check loop stability and consult collateral for inverting buck boost such as https://www.ti.com/lit/pdf/SNVA856, https://www.ti.com/lit/pdf/SLVA933, https://www.ti.com/lit/pdf/SLVA910, https://www.ti.com/lit/pdf/SLYT286, https://www.ti.com/lit/pdf/SLVAE10, https://www.ti.com/lit/pdf/SLVA317.
(3) Additional limitation of 65 V or 100 V exists for switch-node voltage; see the specific data sheet especially regarding the reflected output voltage and the needed clamp circuit.
(4) Depends on specific module and used topology
