It can only filter one checked item. When I check two items, it only shows the first item that I check. Any idea on how the logic would be?

For item As Integer = 0 To CheckedListBox1.CheckedItems.Count - 1
            Dim sql = "select * from Status where Stat= '" & CheckedListBox1.CheckedItems(item) & "'"
            Dim dt As DataTable
            Dim ds As New DataSet
            cnn = New OleDbConnection(connectionString)
                adptr = New OleDbDataAdapter(sql, cnn)
                dt = ds.Tables(0)
                Form5.DataGridView1.DataSource = dt
            Catch ex As Exception
            End Try
            Form5.DataGridView1.Visible = True

You're only populating the DataGridView for individual checked items ... the contents of DataTable dt change each time you go around the loop.

You would be better off building up a list of the checked items first and using that list in a single sql statement e.g. ...
Dim statList As String = "("
For item As Integer = 0 To CheckedListBox1.CheckedItems.Count - 1
    statList += "'" & CheckedListBox1.CheckedItems(item) & "',"
statList = statList.Substring(0, statList.Length - 1) + ")"
Dim sql = "select * from Status where Stat in " + statList
