Is there a difference between 理解する、and 分かる? They all seem to mean "understand"
but I cannot figure their difference:

Here is some context:

> 彼らは誰よりも深くお互いを **理解** し‌た
```

>     They understood each other better than anyone else.
>  
```

Differences between 理解する and 分かる
理解する is very close to わかる in one of its meanings, to understand something.

人の気持ちを理解する - OK

人の気持ちがわかる - OK

理解する is transitive and takes を whereas わかる takes が. 理解する is a kango (漢語) word
consisting of a kanji pair plus suru, so it tends to be used in more formal
contexts.

The use of わかる and わからない to mean "know/don't know" is not interchangeable with
理解する:

brother: 僕のカギどこ？

sister: わからない - OK

brother: 僕のカギどこ？

sister: 理解しない・理解できない - wrong or at least strange-sounding
