I think each personality only actually has 1 emote exclusive to them at high friendship, and then a bunch of other emotes they will tend to teach, but they can teach others if you're missing certain personalities.
If you have Amiibos, you can pretty easily circumvent the DIY issue by inviting one of your missing personalities every day to the campsite and seeing what DIY they offer you. As long as you never complete their requests, they'll keep offering DIYs forever.
