Homebrew Homebrew?

[Pokenisu]

If I have an 11.4 old 3Ds and an 11.4 2DS, and an 11.4 New 3DS and a old 3DS probablynot 11.4, can I do something like a transference or something to homebrew the 3DS?

I think you are referring to DSiWarehax. For that, you will need a CFWed console already, which you can follow this guide on how to do it: http://3ds.guide/
It has everything you need to know about installing CFW. I recommend you start by installing it on the console that has a version lower than 11.4 (11.3 works).
From that point, you can install CFW on the other consoles every week with the DSiWare method. Make sure you read everything though!

PS. CFW = Custom Firmware

If you're talking about the possibility for a custom firmware, no. Impossible without a second 3ds 11.3 and under or a hardmod. If you want very simple Homebrew though, such as rom hacks and emulators, you can do that all be it very specific. For simple homebrew, you need either a PC running Linux capable of making a wifi beacon, a cubic ninja cartridge, a freakyforms cartridge, or an oot3d cartridge and a powersaves. These are your only options, all of which only work on n3ds atm. In my opinion, borrow/ buy a 3ds to mod and do a dsiware transfer to your other 3ds consoles for a full cfw. I also don't normally say this, but you can safely update your consoles to 11.5 if you ever need to. 11.5 only added support for n2dsxl and nothing else.

No, i only want a downgrade to get 11.3 on these 3DS, but I don't find the files to access to Gateway.

You can't downgrade

You can't. If you want to downgrade or install CFW you will need another console with CFW already (so you'll need to find one on 11.3 or less).

I just listed all of your options. There is nothing else at the moment

i have an old 3DS probably not 11.4
So, if I install CFW on these 3DS can I install CFW in the other 3DSs?

As i've said before yes, but you need to actually install cfw first.
