  1. His complacency/complacence on his simple life is adored by many. ‘Complacency’ has negative connotations so does not fit here, even if it is recast so that the grammar is correct.
  2. He believes that people can find peace and contentment in a simple life.

Beeesneees,
1.
‘His complacence on his simple life is adored by many.’
Is this sentence OK?
I think ‘complacence’ is not having negative connotations like ‘complacency’.
2.
‘They attacked ministers for complacence over the dam’s safety when the dam broke.’
Is this sentence OK?
Please correct and comment.
Thanks.

1 - ‘Complacence’ also has negative connotations. It does not work.

2 - Yes, both ‘complacency’ and ‘complacence’ can be used here.

Beeesneees,
‘Guidance on how to comply with the school regulation has been provided in this booklet.’
Is this sentence OK?
Thanks.

Yes, though this has nothing to do with your prior questions.
Perhaps you are confusing
compliance/compliancy/to comply
with
complacence/complacency/to be complacent
