Yes, you can do it. E.g. check out sonoff_dual_lights - two lights controlled by two relays. You can use Siri to control them individually. This example uses a single switch to alter modes (none, first light, second light, both - modeled after my lamp's 4 position switch, but you can add another toggle/button handling and change existing logic to make each toggle/button control it's own light.
Ok..... so I modified the original sonoff basic toggle code. Am i doing it right?

@kalindud yes, you can do it like that. Although since you're dealing with toggle, you might want to match relay state with toggle state. So in your toggle_callback instead of flipping state of your switch, read actual state of a toggle by doing gpio_read(toggle_gpio)
to get it's current state.
Hi, Is it possible to use the same ESP to control multiple Accessories? for example, There are Two Buttons that can control Two separate Lights, and Siri Would be able to Control them separately.
Help? Thanks
