"As far as" VS "As long as"???

Could you check the following sentences are right.

[1] As far as I know, he is right.
[1"] As long as I know, he is right.

[2] As long as I know it, I would immediately get out here.
[2"] If I know it, I would immediately get out here.

I think sometimes I can interchangeably use "as far as" and " as long as". Am I wrong?

Thank you in advance for your teaching.
