DEFINE THEM! Don't only paste parts to your script, you need to define them first, otherwise you'll get errors/warning.
Let's start;
Use GetPlayerName instead of GetPlayerNameEx, or use GetPlayerNameEx(playerid); by adding the following stock

pawn Код:

// At the bottom
stock GetPlayerNameEx(playerid) // <-- This stock for GetPlayerNameEx(playerid);
{
    new nname[MAX_PLAYER_NAME];
    GetPlayerName(playerid, nname, sizeof(nname));
    return nname;
}

Also

pawn Код:

// At the top, under includes/define
forward NameTimer(/* parameters here, if there are */)

// At the bottom
stock Float:GetPointDistanceToPointExMorph(Float:x1,Float:y1,Float:z1,Float:x2,Float:y2,Float:z2)
{
    new Float:x, Float:y, Float:z;
    x = x1-x2;
    y = y1-y2;
    z = z1-z2;
    return floatsqroot(x*x+y*y+z*z);
}
