You've got some mistakes on getting the player's name. Try this one.

pawn Код:

CMD:helpers(playerid, params[])
{
    for(new i; i < MAX_PLAYERS; i++)
    {
        if(GetPVarInt(i, "Helper") == 1)
        {
            if(GetPVarInt(i, "HStatus") == 0) format(string, sizeof(string), "* %s "COL_GREEN"[AVAILABLE]", RemoveUnderScore(i));
            else format(string, sizeof(string), "* %s "COL_RED"[UNAVAILABLE]", RemoveUnderScore(i));
            
            SendClientMessage(playerid, COLOR_LIGHTBLUE, string);
        }
    }
    return 1;
}

Edit: I assume that "RemoveUnderScore" already gets the player's name, so the GetPlayerName isn't necessary.
