First, the sample size is much, much too small.
Personally, I don't look too far into anything with a PF under 1.5 but that's just my personal criterion, and not everyone will agree with it, and it doesn't necessarily mean the systems aren't sensible ones anyway - just that they wouldn't interest me.
I also don't like the average loss being bigger than the average profit (and significantly so, in one case), but against that doesn't necessarily invalidate the thing.
My general sense, given the frequent differences between backtesting results and live results, is that these certainly wouldn't be for me, anyway.
For myself, I'd look no further into them, as they stand, anyway.
Just my perspective, and probably not what you wanted to hear - sorry.
