Depends on what you mean by "Releases". If you mean just the basic elements (fire, earth, wind, water, lightning), then you could technically possess all five, but I would strongly advise against it. If you mean kekkei genkai (e.g, Lava Release, Boil Release, Wood Release, etc.), then, while there is technically no limit, I'd limit it to just one, two at the most.

A word of advice, since you're new here; do not set out to make some super powerful, god character, because you will likely face a lot of cynicism from the other users, including myself, if you do. And secondly, if you plan to make an Uchiha, stay within the bounds of reality. We have too many Madara clones around here as it is.
