ID for four snails? I'm in doubt!

[dinowcookie]

There are four snails of which I'd like an ID. Two of which I thought I had right, but the new two snails I found make me doubt their ID. 
There are two snails I've had for a while that I think are Arianta arbustorum, named Hazel and Morpheus (Hazel seems ill.. I think I may be giving wrong care.) 

These are Hazel and Morpheus compared (Morpheus on the left, Hazel to the right.): 



You can see Morpheus has a near-black body. Hazel is brown-ish (grey body with a brown-ish color on top). Also Morpheus seems to have developed some kind of lip, whereas Hazel hasn't (yet?). You can also see that Hazel is retracted quite deep into her shell. For the past few days she is moving really slowly and she has issues gripping on to things. I've treated her with extra moisture and she eats plenty, but she seems to be doing bad. Here are some more pictures of Hazel. Her shell ends in a weird kind of pointy shape: 



Can anyone confirm that they are indeed Arianta arbustorum? And if not, what do you think they are? I live in the Netherlands where Arianta arbustorum is rather common (less common than Cepaea nemoralis or Helix aspersa). Additionally I would love to learn some more about how to take better care of these two. They seem kinda sad.. 

The thing that made me doubt about their species is two new snails I found, whom I haven't named yet. 
Recently I found a shell of a type of snail I hadn't seen in real life before, and this morning I found another similar looking one: 

 

Because I found these shells, I decided to go out in the garden and try to find live ones of these. 
I was thinking they might have been a subspecies of Mesodon, but it's hard to find ID information about land snails in the Netherlands unfortunately. 

But I was in luck on my search for live ones. I found the following two pretties, the first of which (the one to the right) I had almost mistaken for a Hazel- and Morpheus type snail, because the pattern on its shell is so similar, however it is much less pointy, and when I picked it up I noticed a very distinctive white lip. Can anyone ID these two for me? I think they're the same species, but different sub-species. The one to the left also has some sort of white lip, but not as distinctive. The "golden" snail has a body color like Hazels', grey with a brown-ish color on top. The one with white patches has a dark grey color, like Morpheus. 



 

Here's a comparison of the new white-lipped snail to the left, and my snail Hazel to the right. (Poor hazel ;-; I hope she gets better!)



Can someone help me ID these snails? To make conversation easier, numbers for the snails: 

• 1. Morpheus
• 2. Hazel
• 3. "Gold"-ish snail
• 4. Snail with white patches/white lip

Also, does anyone know what causes these white spot? My snail Mochi has them too, and I see many snails in the garden who have them. 
Are these spots permanent or can they be "fixed" somehow? 
If anyone has the same species/similar snails I would love to see them  

Thanks in advance for any help!

First of all, what gorgeous snails!
Secondly, to help us out with ID'ing your snails, could you tell us which country/state you found them in?
As for the white spots: Those seem to occur naturally with old age, no matter how well you keep your snails. You may have noticed that they seem to 'fade' when the
snails are wet and 'return' when the snails aren't, and as far as I can tell, that's the only way to temporarily rid the snail shell of those white patches.

I've read that some users actually rub canola oil onto their snail's shells to make them brighter, as canola oil is good for many different surfaces (including human hair),
but not much research has been done on whether canola oil is that safe for snails, so I would be careful if you tried something like that.

Thank you I think they're very pretty snails too. I did mention my location in the post, I am in the Netherlands I highlighted it just now so others won't miss it. 
Knowing the location now, do you think you can tell anything more about them? 

I thought the white patches might have something to do with corrosion from some kind of substance, like water with a wrong PH or perhaps bleaching from the sun. 
Someone on this forum has experience bathing their snails with water and coconut oil, which I have used on their shells twice now. It makes them very pretty! 
But I won't do it too often, especially as I think it might be the reason for Hazel being so slow.

All the live ones are A. arbustorum. Mesodon is restricted to the eastern United States so it's unlikely you would find them in the Netherlands. To me those shells just look like they were just young Arianta which have been faded and no longer have the periostracum layer (look at the spot pattern on the first empty shell, it is just like that pattern on the weathered adult Arianta you have). The second empty shell might be another worn out juvenile Arianta which was lighter in coloration or possibly a juvenile yellow Cepaea.

Thank you very much. I am rather surprised  

The reason I thought they were different species is because the shells of the new snails, and also the empty shells I found, are much less pointy than that ones of any A. arbustorum I've seen before. And also I've never seen one with such a distinctive white lip. I can totally see the similarities between Hazel and Morpheus and the other two, but plenty of differences as well.
At least I am happy to now have two new snails, I especially think the golden looking one is quite a unique find, for what you can find around here.

All Arianta should develop a white lip like that once they are fully grown. Yes, the yellow shelled Arianta are less common but not too hard to find if you go to a few "hot spots" and look around for them. In Poland I found 2 yellow ones after a week of looking around.

Interesting seems I'm at luck then, as this was my first time looking for any and I found them within the hour! There's one plant in our garden which I don't know the name of, I'll ask my mom or grandmother later. It was full of snails and these were the 4th and 5th snail I saw in there. All the leaves were part-eaten. You can see one of the leaves of the plant in the picture. I took one along because the snails seem to like it
