I guess you want 2 pages to show video separately, but you Initialized only one page instance and added LayVideoPlayer panel twice on the page. the currently displayed page is generated in the first step，but current lb1.text you want to get and set value is 2nd step. so you could not get and set it.
you should create 2 page instances or 2 exoplayer components to play the videos. when the question is solved, 2nd issue stop video palying will be also ok.

It is same issue as you accessing label, you use only one SimpleExoPlayer to create 2 player instances,
SimpleExoPlayer1.Initialize("SimpleExoPlayer1")
when scroll event is fired, you can only get the first video player handle, so it will not stop the 2nd video playing.
The correct way is that store all of SimpleExoPlayer instances to a list when you initialize them. then get them all to pause video playing in scroll event.

I have commented them in your code.

1.Define a list for player
B4X: 
Sub Class_Globals
    ...
    Dim lb1 As B4XView
    Dim btn1 As B4XView
    Dim PlayerList as List '<==It's for storing player handle
End Sub

2. Add player handle to list in Sub Addstr()
B4X: 
Sub Addstr()
    PlayList.initilize  '<==
    Dim Links() As String
    Links = Array As String("https://download.samplelib.com/mp4/sample-5s.mp4", "https://www.learningcontainer.com/wp-content/uploads/2020/05/sample-mp4-file.mp4" )
    For Each link As String In Links
        Dim s As Info = B4XPages.GetPage("info1")
        Dim YourPlayer As  SimpleExoPlayer   '<==Here use local var for player
        p = xui.CreatePanel("")
        p.Color=Colors.Transparent
        p.SetLayoutAnimated(100,0,0,Root.Width,Root.Height )
        p.LoadLayout("LayVideoPlayer")
        lb1.Text=i
        lb1.Tag=i
        lb1_Click
         btn1.Text="Change" & i
        s.Lvinfo.Add(p,"")
        YourPlayer.Initialize("SimpleExoPlayer1")   '<==
        YourPlayer.Prepare(YourPlayer.CreateUriSource(link)) '<==
        SimpleExoPlayerView1.Player = YourPlayer '<==
        PlayerList.add(YourPlayer)   ' Here store player to List
         i=i+1
    Next
    ' Note:If PlayerLIst is used in other class, here you should assign it to a Process Globals Variable
   '  Process_Globals_Variable = PlayerList

 End Sub

3. Process event
B4X: 
Sub SomeEvent       'You want to do in your event
    for i = 0 to PlayerList.size-1
        PlayerList.get(i).As(SimpleExoPlayer).pause    '<==if Sub is in B4XMainPage
   ' Process_Globals_ariable.get(i).As(SimpleExoPlayer).pause  '<==Some class else
    Next
End Sub
