2) prima ab iuventute = "from early youth," i.e., from a young age.
"From an early age strength grows from exercise of the body." Or possibly "Strength of the body grows from exercise" depending on whether you attribute "corporis" to "vires" or "exercitatione".

6) Should be "oppidum a militibus oppugnatur" with the verb in the singular to match the number of "oppidum."

Your English passives look good other than in #2, which should be "is strengthened." This one is tricky because the plural of "vis" is often just translated at "strength/power" in English, and not with the plural "strengths."
