1. ジムは、あちらでコーヒーを飲んでいるひとです。 2. ボブは、そちらで携帯電話を触っているひとです。 Regarding "texting on his phone", I understand he is using Email or SMS on his phone. We do not have verb "text" that fits in this case. We would say "write an email/message" or something. I did not specify what he is doing on the phone as I guess we are not sure he is actually texting or searching something on the internet from the appearance. I translated the above into "Bob is the person there touching on his phone" in Japanese.
