Hi,
You certainly can install a solution multiple times, but unless the version changes of Plugins/Workflow components, you will replace the previous version. Customisations will always replace the previous customisations.
If only install updates, fields will not be removed from the database - but forms and views will no longer show them.
If you delete a managed solution, the fields will be deleted from the database.
