Views: sort criteria -> Post date, not start from latest but latest-3 is there a possibility to sort articles by postdate, but exclude the latest 3 and start with number 4 (because the latest 3 are already displayed in another view). 

Or even better: is there in general a possibility to exclude articles already displayed on the same page but in another view?
Yes, in the Use Pager options, you can specify an offset, which by default is 0, but can be any number, which, amusingly, in the help section offers:

The number of items to skip. For example, if this field is 3, the first 3 items will be skipped and not displayed.
