            $attributes = $param->getAttributes();

The expression $attributes of type ReflectionAttribute[] is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

                $name = self::getName($attributes);
                $names[$param->name] = $name;

$names of type array is incompatible with the type Ray\Di\ParameterNameMapping|null|string expected by parameter $name of Ray\Di\Name::__construct().

        // name list
        // @Named(varName1=name1, varName2=name2)]
        $this->names = $this->parseName($name);

It seems like $this->parseName($name) of type array or array is incompatible with the declared type Ray\Di\ParameterNameMapping of property $names.

            $exploded = explode('=', $keyValue);
            if (isset($exploded[1])) {
                [$key, $value] = $exploded;
                if (isset($key[0]) && $key[0] === '$') {
                    $key = substr($key, 1);
                }

                $trimedKey = trim((string) $key);

                $names[$trimedKey] = trim($value);
            }
        }

        return $names;

The expression return $names returns the type array which is incompatible with the documented return type Ray\Di\ParameterNameMapping.
