Questions & Answers about Штраф за просрочку и страховой депозит указаны в договоре хранения.
Because the subject is actually two things joined by и:
- штраф
- страховой депозит
Together they form a plural subject, so the predicate must also be plural:
- Штраф ... и страховой депозит указаны ...
- The penalty ... and the security deposit are specified ...
If there were only one item, you would use singular, for example:
- Штраф указан в договоре.
Указаны is the short passive participle plural form of указать.

- are specified
- are stated
- are indicated

- указан — masculine singular
