I have 4 NICs on motherboard and 2 NICs on PCIe card.
The 4 NICs are associated with bridges; the other two are unused.
I would like to use these remaining two to double the speed of the main two NICs (of group of 4 NICs) and as a backup should they fail.

Can this be done if they are already associated with bridges?
How can I do it? I create the bond and then in the bridge what do I put in place of eno1? The identifier "bond1"?
 
Hello,
Yes, just replace the old interface name by bond name in /etc/network/interfaces ( on vmbr )
Don t forguet to define bondX as manual in the same file

Does the hardware switch or network card need to have any special features?
My switch doesn't support LACP. To double the bandwidth and have a backup which option is preferable?

If your switch isn'T supporting 802.3ad and you want more bandwidth + failover there are only "balance-xor" and "balance-rr". In both cases you should only see a bandwidth increase if different hosts try to access your PVE at the same time. I single connection won't be faster than 1 Gbit if these are 1 Gbit NICs.
