Sample
Private key: 1000

Information you give me
If you give your private key 1000 public

1000-1 = 999 public key
1000 +1 = 1001 public key

1000 + 500 = 1500 public key
1000-500 = 500 public key
If I know the public key of 999,1001,1500,500
My information
Will it help me find my Bitcoin private key?

Of course. If you know this exact step between the known public key and target public key you will find the private for the target one. I mean if you know 1 and 500 in your example. But is these steps are just x and y - so no.
And also you should know the PRIVATE key from 1000+500, 1000-500, etc, not public one. Knowing just public is not enough because public key is just an ECDSA addition of 2 points.
