What does my oppenent have? (local live game)

[Spuddy]

So far everyone has "touched" the correct responses.

Hand One:
10-8 of di

Hand Two:
A-4

Also, is my re-raise of the min bet poor?
As for whether or not his min-raise was strength or not, I should have thought about that more. My friend suggested that I flat call the raise, and check the turn and see what he does and then re-evalutate.
