Hello,

is there a way to open several sessions at once by putty with a Windows 
command or somehow other; if yes, how?

sure, putty has command line options that let you do things like this.
For example, something this would work in a batch file:
putty -ssh -l myid -pw mypassword whatever.whereever.com
