Sorry if such topic already discussed but I found nothing about it.

Is it possible to find all PHP classes that belongs to some namespace?

I tried to look at FileBasesIndex and Stub index in PHP open API but could not find proper way how it could be done

First, you need to collect all classes, then filter them by a namespace. Note: the same set of methods exists for interfaces and traits.

final Collection<PhpClass> result = new THashSet<>();
final PhpIndex index = PhpIndex.getInstance(project);
final Collection<String> names = index.getAllClassNames(prefixMatcher);
for (final String name : names) {
  final Collection<PhpClass> classes = index.getClassesByName(name);
  final Collection<PhpClass> filteredClasses = index.filterByNamespace(classes, namespaceName);
  result.addAll(filteredClasses);
}
