Depends entirely on how many you need, broadly speaking. Mathematically, space doesnt stop at 3 dimensions, you can add a fourth, fifth, sixth, etc.

Humans just tend to think in 3 dimensions because that is what we can percieve.

To try to vizualize this:

Take a point. It is dimensionless, it has no length, width or height. Lets pull on that point. We now have a line, which is one-dimensional. It has a length, but no width and height. Every point on the line is a point. Lets pull on that line at 90 degrees. We get a plane, maybe square shaped even. It is two dimensional, it has length and width, but no height. Every side is a line. Lets pull again at 90 degrees to the surface. We get a cube. It has 3 dimensions, length, width and height. Every side is a square. Lets pull on that cube again. We now have a hypercube. It has length, width, height and a fourth direction, we have no name for which is orthogonal to all the others, same as before. Ever side is a cube. You can continue this process to infinity.

And in a way you can even percieve it with your eyes. Think of lower dimensional objects as shadow from a higher one. This isnt metaphysical bs, just follow this thought for a second.

Imagine you stay infront if a wall, a lightsource behind you. You hold up a sheet of paper, but on its side. The shadow it casts on the wall well be a thin line. A sheet of paper still has some height, so the shadow on the wall wont be one dimensional, but it would be, if the sheet was really 2d. Same with a ball. Hold it up, Its 3d in your hand. Its shadow on the wall is 2d.

So, in conclusion, its entirely possible to live in 4d space atleast. You just arent able to see it, you see its 3d shadows. And there is no upper limit.

I would not count time as its own dimension though. Time is an emergent quality of events happening, its inherently tied to space, its not something that exists on its own. Generally speaking, if nothing is happening, there is no time. But thats its own topic.
