Do you have some kind of theme going on? Are there things they have in common design-wise? Because if not, I think it's just a matter of opinion and of which villagers you like best.
Personally, I would replace Pashmina with Frita. Both of them are great, but I think that Pashmina matches villagers like Fang and Diana so much better. Frita just looks sort of out of place on your list.
Chevre and Apple could both look nice, but I agree that Chevre would look nicer.
I'm not sure who Ronald is, do you mean Roald? I think that Roald seems more subtle and more fitting for your town than Rod.
Punchy and Deli would look good in your town, both of them, but between them I think I'd choose Deli. It seems like a more unique and original choice for your town.
I think that villagers like Nana, Cookie, Merry, and some others with that sort of design would look nice in your town.
That's just my opinion, of course.

To find people who are giving away villagers, keep an eye on the threads in the Villager Trading Plaza. You can also do a search there (using the search button) to find threads where people have been giving them away recently. There's a thread where you can post about villagers you're looking for and giving away, too. Whenever I've given away villagers, that's helped me get in touch with people who were interested in them. It's here:
