How to properly load all the chats?

Following the Java example, I recursively call the LoadChats method until I get a 404 error. However, I get this error even when less than half of the chats are loaded.

See https://core.telegram.org/tdlib/getting-started#getting-the-lists-of-chats. Basically, you need to listen to updates and change chat order based on the updates. If you receive 404 from loadChats, then all relevant updates has already been sent.

And how do I control the order of updates? For example, if the chat update event came with chatId before I got it from newChatUpdate.

And so, if I need to load messages from all ChatList then I need to call multiple times loadChats with the required chatList? Until I call loadChats from ChatListArchive or ChatListFolder, the chat updates won't come from there?

The updates for a chat list can be received if loading of the chat list is required to answer some other request besides loadChats.
