Answer

You are right (about "ありますか" and "いますか"), we use "いる" for people and "ある" for things.

Are there a lot of foreigners in Japan? -> 日本には外国人がたくさんいますか? (as you said)
Are there a lot/many foreigners living in Japan? -> 日本に住んでいる（すんでいる）外国人はたくさんいますか?

Answer

日本には外国人がたくさんいますか？is 100% correct and natural:)
Are there a lot/many foreigners living in Japan?=日本には外国人がたくさん住（す）んでいますか？
