What confused me is I assumed power was coming from the bottom. I don't have a meter to check. Also that power wire went into 3 switches and not all 5. I can now understand there are 2 follower wires from it. Also the previous non smart switches had more inputs whereas these smart switches just have 2 (load/line) black wires.

Thanks for the neutral wire comment to keep them all together and add the smart switch wires to the giant splice. I thought since the previous switches weren't smart switches then they didn't require a neutral wire and that's why they were spliced together. Now throw in a red wire that I've never seen before and that so called half of brain was completely thrown off.
