2 fax machines on 1 line working simultaneously???

For reliability purposes is it possible to have 2 fax machines on 1
line and receiving faxes simultaneously on both of them. If so, how to
connect them.

This is not possible.
Before the page is transmitted, both fax machines (originating and
answering) exchange messages and negotiate the parameters for the
subsequent transmission.
If you connect 2 fax machines in parallel both fax machines will answer
simultaneously and the signals will interfere.

Can I adjust these fax machines by different number of zooms (for
instance the first one after 2nd zoom and another after 5th zoom) and
get working just the first one? In case if the first one is out of
order would the second one work?

This is an interesting idea - and it could work!

I just tested this with a fax machine in parallel to a fax modem. The
fax modem was connected to a PC and I used VentaFax as fax SW.
The fax machine was set to answer after the 5th ring and the VentaFax
SW was set to answer either after the first ring (during the first
test) or after the 10th ring (during the second test).
The result was as expected: In the first test the fax modem answered
the call and in the second test the fax machine answered the call.

Although these tests were promising, you should in any case repeat
these tests with your own fax equipment.
Connecting two fax machines in parallel is not a standard configuration
and might result in distorted signals.
Furthermore you should keep in mind that the backup fax machine will
only take over if the first fax machine doesn't answer to the ring. It
will not take over if the first fax machine fails due to any other
fault, e.g. in case of missing paper...

Thank you for your test!!!!!!!!!!!!!!!!!!!!!!!!!!!
