"Can somebody here give a definition for all ordinals higher than that"

That's an impossible task, even in theory.

I assume you meant:

"Can somebody here give a definition for all the ordinals that has been used on this wiki"

Unfortunately, when we add the constraint that a beginner must understand these definitions, this - too - is an impossible task.

My recommendation to you is to proceed one step at a time and expand your horizons slowly.

And remember: the journey never ends! No matter how deep and seemingly complete our understanding is, there will always be something more just beyond the horizon. That's the nature of ordinals (and the nature of numbers, really).
