Hard to say as always in pics but I would lay odds you have two capensis and yep that big gal is a fuliginosus.

On getting tagged, if is does happen my advice is let it happen do not pull back. House Snakes have about the longest teeth relative to size I have ever seen. I have been tagged a bunch of times by one of my young wild caught females. Never any pain, always some blood and she is still very small. My wife got tagged by her and jerked back, quite a bit of blood and a bit of sting for such a small snake.

I have had a few nips by some bigger ones too, again no pain and just the typical tiny holes that bleed. So do not sweat it and if one takes a chomp again no pulling back. Overall most of them are wonderful in attitude though. With the exception of the one b*&!ch all my other tags have been from inside a hide with I am sure the expectation of feeding time and all of those have been very mild,
