Not sure how #1 would be implemented - everything needs a gene attached to it and anything controllable needs output neurons, so if Bibites could gain and lose these dynamic parts there would need to be something in place to handle Bibites having different amounts of output neurons.
#13 could be implemented by splitting the map into quadrants - Northeast, Northwest, Southeast, and Southwest. Then, depending on what quadrant a Bibite is in and what border is being crossed, the Bibite could basically be teleported. Going off the east edge would put you on the west edge, and vice versa. Going off the north edge will put you back on the north edge but in the other direction, and same for the south edge.
I don’t quite understand what you mean with #5 - is this, like, egg merging?
