Hi,
Welcome to Toolset support.
The "This block was translated via WPML" boxes in your editor screenshot are WPML's lock on a translated page.
They say to edit the page in WPML's Translation Editor.
So the conditionals look broken in the editor because it shows those placeholders, not your live blocks.
Judge the result on the front end.
Going through your points:
For items 1 and 5 I suggest that you switch to manual transltion instead of the Advanced Translation Editor as complex inner texts inside conditionals might have issues with the editor.

2. Forms and Content Templates are translated separately.
In "WPML → Translation Dashboard", send your form ("Toolset Forms") and any Content Template with the links.
3. Types fields have a translation option in "WPML → Settings → Custom Fields Translation" (wpcf- fields). I would suggest that you use the manual translation for that specific page.
4. A translated form is a separate item. If your PHP checks the form ID, make sure it matches the translated form.

To translate this page manually in the WordPress editor:
1. Edit the page in your default language.
2. In the "Language" section on the right, click the "WordPress Editor" tab under "Translate this Document".
3. In the pop-up, select "Only this page" and click "Apply".
4. In the table that appears, if the translation does not exist yet, select the "Duplicate" checkbox next to your language and click "Duplicate". If it already exists, skip this step.
5. Click the pencil icon next to the language. Replace the text with translations, including the text inside the Conditional blocks and the link text. Then click "Save".
After this, do not use the WPML Translation Editor or automatic translation on this page. They overwrite the page with the layout of the original.
