Aside from the Pokemon you listed (Slaking, Archeops, and Regigigas) and their pre-evolutions (Slakoth and Archen), there are a couple more, being Durant with Truant, Audino, Bewear, Buneary, Golett, Golurk, Lopunny, Stufful, Swoobat, Toxel, and Woobat with Klutz, and Sableye with Stall.
For Durant, Sableye, and the Pokemon with Klutz, they can be obtained without these abilities, and you may also use an Ability Patch on them to change their ability to be their hidden abilities (though, this won't work in the case of Audino, Toxel, and Durant, as Klutz/Truant are their HAs). Audino and Woobat/Swoobat can also Skill Swap Klutz to the opponent in place of their abilities.
For a in-battle workaround for these abilities, as well as a workaround for the Pokemon who don't have alternative abilities to use in place of their hindering abilities, you can find in of my previous answers to another question, being this one.
I hope I helped!
