渡辺さんも回答しているように、英語には「取り皿」という単語がないので通常の単語を使うしかありませんが、具体的に何をする（したい）ための皿かを添えれば伝えることができます。
英訳1：Could we get some small plates?「小皿をいただけますか？」
英訳2：Could we get some extra dishes?「余分にお皿をいただけますか？」
plateをdishに換えてもOKです。
英訳3：Could we get some plates for sharing?「取り分けたいのでお皿をいただけますか？」
こう言えば、給仕の人にうまく通じるので自然な表現でしょう。
こんにちは！
英語では「小皿」や「取り皿」という決まった言い方がないのですが、シェアするためにお皿をもらう時に一般的なのは small plates という言い方です。直訳は「小さい皿」なのでほとんど「小皿」だと思っても良いですね。extra plates（追加の皿）と言ってもオッケーです。
We want to share（シェアしたいんです）とか so we can share（シェアできるように）と付け加えれば確実に伝わりますよ。
例：
Erik: Can we have some small plates? We want to share.
小皿いくつかもらえますか？シェアしたいんです。
Waiter: No problem. I'll be right back.
かしこまりました。すぐ戻ります。
ぜひ参考にしてください。
1)Could we please have some extra plates.- This means you are requesting for extra plate. However you can be direct and mention the number, like the second sentence. At least the waitress will know exactly how many you want.
1）Could we please have some extra plates.
（もう一つプレートを頂けますか.）
これはもう一つ、別のプレートがほしい事を意味しています。
しかし、2番目のセンテンスのように、直接数を伝える事もできます。
この場合、少なくともウェイトレスは、必要なお皿の数を正確に知ることができます。
Well, you could specify exactly how many extra plates you need. It is not necessary to say you want to share as it will clear in context anyway, - you are the paying customer, right!
"Two extra plates please!"
"Certainly madam!"
If a group of friends arrive at the same time, a blanket request may be:
"Extra plates and cutlery please!" How are these people going to eat without cutlery? With their hands?
何皿欲しいか行ってあげても良いと思います。シェア用っていうのは文脈で明らかなので言う必要もないです。
例：
"Two extra plates please!"
"Certainly madam!"
友達のグループも一緒にきたのなら、食器がないといけないので
"Extra plates and cutlery please!" カトラリーとお皿お願いします。

Sometimes when you go to a restaurant, the waitress serves the food for two people on one plate.
It's just the way they serve food in some restaurants.
If you have company, and you would like that you and your companion share the food, you can ask for a plate with a double portion.

時々、レストランに行くとウエイトレスが1つの皿に2人分の食べ物を運んできます。
レストランでの提供方法です。
もし、連れの人がいて、食べ物をその人と分けたいのであれば、もう一度皿を頼むことができます。
At a restaurant a dish on the menu, or a dish chosen by diners, can be shared between them. There can more than 2 diners sharing a plate, if it is large enough to go around.
Example sentence: This restaurant is popular for its sharing plates.

Either question should get you some more plates so that you can share. You could also add something like 'Thank you - we'd like them so that we can share food.'

These are both easy and polite ways to express this to someone.

ご質問どうもありがとうございます。
様々な表現があると思いますが、いくつか自然な表現を紹介します。
- Could we get some extra plates, please?
- Could you bring us a few extra plates, please?
お好みに合わせて使い分けてみてください。
ご参考にしていただければ幸いです。
Please could you get me some extra plates so we can share this food? Thanks
Were going to share, so please could you get me some extra plates?
Saying 'please' and 'thank you' is a nice and polite way of asking for what you want.
It is seen as extremely rude when you ask for something but dont use manners like please and thank you.
You would need extra plates when sharing food, so when asking, you should say you would like extra food.
This question is asked in a pretty straight forward way but can be changed in slight ways and still come out with the same meaning. First its good to mention that you can use, "could," and, "can," interchangeably here, and that it's totally up to you if you want to include the phrase, "for sharing," to explain the purpose of needing/wanting the extra plates.
