First, learn to ask questions. What is "multisite"? Google does not google anything intelligible for this word.
On this topic:
different bases - it is theoretically possible, but practically inconvenient (and has no special advantages). With different databases, your application must have advanced rights to create these databases, create users and grant them rights. Assuming that the tables in each database will be different, then how will the overall application code work with this?
Therefore, it is easier to have one pre-created database with a universal table structure, each table has a site_id column and filter all data by this column.
Different views - this is done quite simply with the help of prepend_view_path

class ApplicationController < ActionController::Base
  before_action :detect_site

  def detect_site
    @current_site = Site.find_by(host: request.host)
    prepend_view_path "app/views/sites/#{@current_site.name}"
  end

  helper :current_site
end
