how does the change get suggested? also who does not want to accept a change does have to upgrade anyway and accept it anyway?
Hi, first of all I got a simple question.
Im running bitcoincore on a centos server with 1gb ram, which is downloading the blockchain in prune mode really slow (now it's at 338k and downloads 10 blocks a minute....),
can I download the blockchain on my computer and import it to the core even if it's in prune mode?

You can, but that would be slower.
(download 600mb in prune mode and upload to the server)
No. Bitcoin Core needs to process all the blocks from the past so it can build the UTXO.
I see that forks are made if 51% of nodes give the consensus,
That is not correct.
but if you make 1kk (1'000'000) virtual machines with bitcoin core, and those are the 51% You could actually submit a bip and get it verified instantly
That is not how the BIP process works. Nodes don't get to vote on BIP. They can accept a change, or they can refuse to accept a change, but they can't choose which changes the other nodes choose to accept.
leading the possibility to adopt a new change that could affect and steal everyone's bitcoins or make an actual change that everyone pays a default fee to the attacker's address?
Nope. Can't happen unless an overwhelming number of acutal users (merchants, miners, wallet creators, etc) all choose to accept the change.

The 51% attack is regarded as successfull if you can compromise/gain control over 51% of the networks computation power (here: hash rate).
So your 1.000.000 virtual machines would be useless until they had hosting machines which would raise those 51% of the total hash rate (in this case 1 host theoretically would be enough.
Currently the hashrate is at about 8,481,426,000 GH/s (Source: https://bitcoinwisdom.com/bitcoin/difficulty).
No one? thanks fams :\

Second question:
