It shows only one person because you are showing the dialog after you find the first person. You need to show it after getting all the players.

Код:

dcmd_admins(playerid,params[])
{
    #pragma unused params
    new count=0,string[128],rank[128];
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(IsPlayerConnected(i) && GetInfo(i,"AdminLevel")>= 1)
        {
            format(string, 128, "{FF02A7}%s              {ffffff}Level: %d", AdminName(i),GetInfo(i,"AdminLevel"));
            count++;
        }
    }
    if(count) ShowPlayerDialog(playerid, 5559, DIALOG_STYLE_MSGBOX, "Online administrator", string, "Close", "");
    if (count == 0) SendClientMessage(playerid,LIGHTBLUE,"{FF02A7}[Admin]:{ffffff}There Are no Admins Online");
    return 1;
}

Btw, this will again not work because you need to use fomat and strcat to add all players to the string.
