It's normally recommended to have two cables so that you have a ring rather than just a chain. Don't forget to configure MAD BFD as well!

That varies from model to model, but there should be an IRF configuration guide for your switch which will take you through it step by step.

Two-chassis IRF fabric can only be daisy chained.

Apologies for my inaccuracy, it is not a true ring, but the daisy chain can have redundant links with dual cables.
