Shouldnt be an issue at all. What size is the tank though?
Yep, you can run any amount of filtration in your aquarium as long as the output is not too strong as some fish dislike strong flow whilst others crave it. I am going to run a tank with multiple filtration soon. its a great Idea for fish that produce a heavy bio load
I run hob and canisters, hob and undergravel filters.
Yes you can.
