How to combine macros?

Question

Macros

Please tell me how to combine 3 macros into one? If it's not difficult to write the correct
PS code, an amateur in this topic

The first macro (odin) displays the name of the pdf files in the folder and the number of sheets and displays the data on sheet1

Sub Odin()
    Dim I As Long
    Dim xRg As Range
    Dim xStr As String
    Dim xFd As FileDialog
    Dim xFdItem As Variant
    Dim xFileName As String
    Dim xFileNum As Long
    Dim RegExp As Object
    Set xFd = Application.FileDialog(msoFileDialogFolderPicker)
    If xFd.Show = -1 Then
        xFdItem = xFd.SelectedItems(1) & Application.PathSeparator
        xFileName = Dir(xFdItem & "*.pdf", vbDirectory)
        Set xRg = Range("A1")
        Range("A:B").ClearContents

        I = 1
        xStr = ""
        Do While xFileName <> ""
            Cells(I, 1) = xFileName
            Set RegExp = CreateObject("VBscript.RegExp")
            RegExp.Global = True
            RegExp.Pattern = "/Type\s*/Page[^s]"
            xFileNum = FreeFile
            Open (xFdItem & xFileName) For Binary As #xFileNum
                xStr = Space(LOF(xFileNum))
                Get #xFileNum, , xStr
            Close #xFileNum
            Cells(I, 2) = RegExp.Execute(xStr).Count
            I = I + 1
            xFileName = Dir
        Loop
        Columns("A:B").AutoFit
    End If
End Sub

The second macro (dwa) displays the name of the pdf files in the folder and adds hyperlinks to pdf files and outputs data to sheet1

Sub Dva()
'Update 20150831
    Dim xFSO As Object
    Dim xFolder As Object
    Dim xFile As Object
    Dim xFiDialog As FileDialog
    Dim xPath As String
    Dim I As Integer
    Set xFiDialog = Application.FileDialog(msoFileDialogFolderPicker)
    If xFiDialog.Show = -1 Then
        xPath = xFiDialog.SelectedItems(1)
    End If
    Set xFiDialog = Nothing
    If xPath = "" Then Exit Sub
    Set xFSO = CreateObject("Scripting.FileSystemObject")
    Set xFolder = xFSO.GetFolder(xPath)
    For Each xFile In xFolder.Files
        I = I + 1
        ActiveSheet.Hyperlinks.Add Cells(I, 1), xFile.Path, , , xFile.Name
    Next
End Sub

Thank you in advance!!!
