Generating a SHA256 Hash from another Hash

[Xsample]

So basically what you're saying is that if someone had a word list of sha256 hashes they could just brute force that list against the current hash and hope to find a hash that would generate the current hash they know?

So taking my example

Starting Hash

bc6f622525292996fbd592a1dcdaf7de33c8f2983d223a62a34f13d36390c05f

Then using the above hash to generate this hash.

Then using the above hash to generate this hash.

my main question was if you had lets say 100 hashes that were generated from 1 SHA256 hash that if you knew 99 of those hashes it does it or doesn't it make it any easier to crack the last hash in the chain?

Use the above hash to generate 99 Hashes

Hacker knows all 99 hashes but doesn't know starting hash. Does having the 99 hashes that where generated from the
"Starting Hash" make cracking it any easier?

Hopefully that makes sense.
