How Many Animals Did Moses Take Into The Ark?

According to the story in Genesis, Noah was first told to collect two of every animal. A little later this is changed to 'Of every clean beast thou shalt take to thee by sevens, the male and his female' and the 'unclean' beasts to be taken in twos as before ('clean' refers to Jewish dietary laws here.)
Total numbers aren't given, but as the Ark is described as being only 300 cubits long (a cubit could be anything from a bit over a foot to a yard) and you couldn't fit  a fraction of all the world's creatures into such a space, it's clear that the story isn't meant to be taken literally.

2 of every kind

It wasn't Moses who brought the animals on the Ark, it was Noah. That's why they call it "Noah's Ark"! Noah brought one of each species, one male and one female, in order for them to reproduce!

,it was Noah's Ark not Moses. Jehovah told him: “Go, you and all your household, into the ark, because you are the one I have seen to be righteous before me among this generation. Of every clean beast you must take to yourself by sevens,
the sire and its mate; and of every beast that is not clean just two, the sire and its mate.”
So “seven seven” in Genesis 7:2 does not mean seven pairs, or 14, just as the repeating of “two” does not mean two pairs, or four, in Genesis 7:9, 15. The repetition of a number in each verse merely denotes a distribution—not an addition of the numbers. Hence, while clean animals were taken into the ark “by sevens,” of the unclean ones, “just two” were taken.
What, though, of the expression “the sire and its mate” immediately after the word “sevens” at Genesis 7:2? That has led some to think that Noah was instructed to take seven pairs of every kind of clean animal. The clean beasts, however, were preserved not strictly for the purpose of procreation. Genesis 8:20 tells us that after coming out of the ark, “Noah began to build an altar to Jehovah and to take some of all the clean beasts and of all the clean flying creatures and to offer burnt offerings upon the altar.” Having on hand the seventh animal from each clean kind provided Noah with an animal for sacrifice, leaving three mated pairs for propagating their kind on the earth.....I hope this answers your question.

None. It was Noah who built the ark.

He took 2 of every kind
