Yes, it is always okay to ask questions. However, I would reccomend to keep your tone polite, always leave room for more knowledge. If you want to acquire intelligence, you must be willing to be accepting it humbly.
You might find people in the world who will laugh at you sometimes but let me tell you this, those people will never actually find true success. Don't hesitate to be inquisitive.
Wisdom increases on sharing and questioning.
