Can multiple RJ45 cables be connected in parallel between a box and a switch?

Hello,
Everything is in the question. ;-)
I have a box (SFR Business Fiber) that has 4 RJ45 ports.
Is there any benefit to multiplying the cables between the box and the switch in my patch panel?
Same question between my switch and my server running Windows Server 2012 (which is mainly used for file sharing on the local network).
(For your information, my server has 3 RJ45 ports: one marked 1, one marked "2," and one marked... "M"!)
And finally, the same question between the server and the box.
For example, if there is a benefit, I could put 3 cables between my box and my switch, 1 cable between my box and my server, and 1 (or 2) cables between my server and my switch.
----- Current config:
Acer Atos AT310F2 Server
Internet connection via ADSL box (I have not yet connected the fiber to the network).
1 cable between the server (port 1, the other 2 RJ45 ports on my server are not used) and the switch
1 cable between the switch and the ADSL box
... and plenty of cables (Cat 5e) between the switch and my patch panel. ;-)
Thank you in advance if someone knows how to respond!

Hello,
without overdoing it, definitely not,
you risk generating a network loop that paralyzes everything.
You need to have a manageable switch to create port groups (trunk) 802.3ad (LACP).
Under Windows Server, it's called teaming.
Between the internet box and the switch, I think it would be useless, most of the time the LAN being gigabit and the fiber connection being less than gigabit.
On a NAS, it depends on the NAS, there is often the possibility of port aggregation (bonding)
But if we do not configure aggregation on the switch side, we must absolutely not connect multiple ports to the same machine (except different VLANs, but that's another matter) for fear of a network loop, especially between the box and the switch without spanning-tree.
