6 handed limit hand range.

After about 25K hands at 5/10 I'm just going through some of my PT positional stats and picking out a few hands that I may or may not be misplaying or maybe I shouldn't be playing them at all. I've lost more than I should with these hands or it might just be variance.

KTs, KTo, K9s, K9o, QTs, QTo, Q9o, J9o, JTo, 9To,

Which are MP but not UTG or even just CO or Button?

I have made a little with JTo and 9To UTG so I'm thnking that the other hands hands might just come around eventually and that I might have been playing them poorly. I've also lost a lot in MP with QTo and Q9o but not with J9o. Overall I've lost a lot more than I've won in all positions with this group so I think I have to be doing something wrong.
