Welcome to the forum.
The short answer to your answer is yes, it will help your score go up. The more history and age, the more it will help. The things that you need to be aware of is make sure you make your payments on time. The other is watch what balance gets reported. If you have a card with a $10k limit and each month you spend $5k on it, if you let the statement close with a $5k balance your utilization on the card will report at 50%. Do your best to not let the card report more than a 20% utilization, and the same goes for total credit utilization. If you have more than 1 card, try to let only 1 card report a balance and a minimal one at that.
