Hey,
I am new to ball pythons but not to snakes in genaral. Most snakes I House together, if they are the same size, don't have too much trouble with each other but, it still probally a good idea to give each snake its own enclosure if at all possible.

For a name for you chameleon mabey sticky or iggy.

As far as crickets in your computer, I don't think they will cause major damage but not sure on that.
