Yes, this is a custom function written in wordpress. You won't fine "handler" in regular php documentation since it's it's really just an argument to the wp_enqueue_style function defined in the wordpress ecosystem.

Handler can be any valid string. You get to decide.

so handle just a reference of an object or to give a name to that object just like identifier ??

Basically. If you look at the example below on the link I provided, in the Load stylesheet only on a plugin's options page example you can see they use wp_register_style with a handler, and than later they just call wp_enqueue_style with only the same handler name as an argument, and it works.
