Which minecraft server was there in the old alpha?

"Already" means it must still exist?

Do you mean "old alpha" simply the alpha version? So the version from 2009/2010.

Hä musss es why is there in he old alpha multiplayer mode

Because there were servers back then. But that one has survived until now is questionable. It also depends on whether you simply mean alpha with Old Alpha.

One of the oldest is 2b2t, but there was no real multiplayer in Alpha

2b2t
MinecraftOnline
Crazy Fools UK
Nerd.nu
minr.org

These are all servers that were already in Alpha that still exist.

Old alphaa is at minecraft launcher why

This simply means alpha. Do not ask me why they called it old_Alpha in launcher, think you wanted to make it clear to new users that the versions are very old.
