So I have this planet where I want the middle to (as in where the equator would be) to have all four seasons instead of mostly tropical like earth and am not sure how to do that to make it realistic with axis’s and stuff.

I’m also thinking about giving my planet 7 moons, the reason being the planet has been destroyed at least 6-7 times and the moons are what was left over from the old planets. And I’m not sure how much that would affect my planets gravity, tides, ect.

Does anyone have any knowledge or tips on how to do this?

Not sure if you're still interested, but planetary mechanics are fun.
If you want your equator to have all 4 seasons, you could have the planet rotate on it's side, similar to Uranus. The east/west equator would experience seasons slowly as the planet orbits the sun. The north/south axis would be the part that spins and creates your day/night cycle. That part of your planet could also experience seasons by having the planet have an elliptical orbit (more of an oval than a circle). When it's in the closest part of its orbit =summer; when it's at the farthest point= winter. That way your whole planet experiences seasons, even if the seasons don't come at the same time. This would also give it kinda extreme seasons, and that can be fun to mess with.

So Luna (Earth's moon) is roughly .12% the mass of earth, and it creates our tides. But the moons around Jupiter, despite being huge, don't really affect gravity or gasses on surface of the gas giant; because Jupiter is HUGE. So it really depends on how big your planet and moons are. Also, gravity is measured using a formula that includes the mass of the two objects and the distance between them. So it also depends on how far your moons are from the surface of the planet.
Another thing to think about with this is how the moons interact with each other. Research shows that the Galilean moons of Jupiter, which all have oceans, affect EACH OTHER more than they affect Jupiter. Furthermore, despite Jupiter being huge, the moons passing each other has the higher gravitational effect on their tides and stuff. Which is super cool.
