Normal: The TSH is the most accurate test in a "stable" situation, that is no significant new changes.

Normal: Your thyroid values are normal. Many of the tests that were run on you don't help in diagnosis and are just a waste of blood and money.

Normal, in context: Though the T4 & the free (direct) T4 levels are at the lower limit of normal range, do not put too much emphasis on it. The T4 (and, therefore, the free T4) levels can vary a bit during the course of the day. Remember, these are hormones, and so there is some variation depending on how much the gland is putting out and the body is using THAT INSTANT. The TSH is your better guide, and it's normal.
