"My friend Bob has a question."
Translation:صَديقي بوب عِنْدهُ سُؤال.
Yes, it is true. If a sentence has a verb you can begin with the verb or with the subject or with the preposition while making the suitable changes. What comes first is emphasized.
You also have to take into account that in the example above, the Arabic sentence has no verb, it is a nominative sentence with no verb (the verb "has" is implied using the adverb عند).
