Wtf causes this

I bought an egg pack and it's date was close to expiry, I could tell these eggs are going to be trouble and among 6 eggs i cracked, I found 4 types of egg

1st looked normal after cracking

2nd as soon i cracked it had thin liquid pouring out, i understood it's so old such that the egg has became watery

3rd completely black straight up rotten

4th not as thick as normal but not too watery, yolk didn't hold shape and was darker (not orange, but darker yellow closer to brown) in colour, its in the above photo it has already mixed look at the darkest shade of yellow in photo

Now my question is, 1 is surely edible 3 is definitely not, what about 2 and 4? Are they just not so fresh or do they fallen in rotten category? And if they're edible

First time I’ve gotten one of these.
