You can combine GetPlayerPos with IsPlayerInRangeOfPoint, like this

pawn Код:

CMD:givemoney(playerid, params[])
{
    new amount, Float:Pos[3];
    if(sscanf(params, "ui", targetid, amount)) return SendClientMessage(playerid, -1, "[USAGE] /givemoney <playerid> <amount>");
    GetPlayerPos(targetid, Pos[0], Pos[1], Pos[2]);
    if(IsPlayerInRangeOfPoint(playerid, 5, Pos[0], Pos[1], Pos[2])
    {
        GivePlayerMoney(targetid, amount);
        GivePlayerMoney(playerid, -amount);
    }
    return 1;
}
