Select data even if it does not appear on all tables

I have the following Query :

SELECT 
    public.suprimento.suprimento, 
    public.estoque.numeroserie, 
    public.fornecedor.nome as fornecedor, 
    public.estoque.data as dataentrada, 
    public.estoque.numeronotafiscal,
    public.empresa.nome as empresa,
    public.entrega.data as datasaida,
    public.entrega.notafiscalhss,
    public.entrega.usuario,
    public.entrega.usuariohss,
    public.lotesretornosuprimento.dataretorno,
    public.lotesretornosuprimento.laudo,
    public.lotesgarantiastatus.numeroserieretornado
FROM
    public.estoque, 
    public.suprimento,
    public.fornecedor,
    public.entregaitem,
    public.entrega,
    public.empresa,
    public.lotesretornosuprimento,
    public.lotesgarantiastatus
where 
    public.suprimento.codigo = public.estoque.codigosuprimento and
    public.estoque.codigofornecedor = public.fornecedor.codigo and
    public.entregaitem.codigoestoque = public.estoque.codigo and 
    public.entregaitem.codigoentrega = public.entrega.codigo and
    public.empresa.codigo = public.entrega.codigoempresa and
    public.lotesretornosuprimento.numeroserie = public.estoque.numeroserie and
    public.lotesgarantiastatus.numeroserieenviado = public.estoque.numeroserie

That returns me the whole course of the supply from the moment it is bought until the return to our supplier for correct disposal or for guarantee, my need however is to also display the supplies that way bought but still were not sent to any client or returned to the vendor, in the way I mounted the Query I only select the supplies that had the complete track:

Purchase - > Sale - > Return Supplier

It is possible to adapt this Query so that it also returns the following situations:

Purchase - > Sale

And also when the supply is only purchased:

Buy
