Which is lighter, the Hoka Arahi 4 or the Arahi 5?

Neither by a meaningful margin. Both weigh about 9.6 oz in a men's US 9.

Do the Hoka Arahi 4 and Arahi 5 come in the same widths?

Yes. Both run in D, 2E for men's sizes, so a width that fit in the Arahi 4 carries over to the Arahi 5.

How do the stack heights compare?

29 mm heel and 24 mm forefoot on the Hoka Arahi 4, against 29 mm and 24 mm on the Arahi 5. Same platform under both.

Is the Arahi 5 still the newest Arahi?

No. The Arahi 6 replaced it in 2022, so the Arahi 5 now sells as an older model and usually below its $130 list price.
