Answer 1

As a rule, always name your constraints. In this case, there are 3 constraints on the table and the names SYS_C* are unhelpful to determine which constraint is being violated.
In the first error, look at the last 2 columns in the PLC table. You try to insert '1' and '1', but those values do not exist in the PROGRAMATOR and VYROBCE tables. The values in these tables have the suffix of 'P' and 'V' respectively. So the insert into PLC should reference '1P' and '1V'
As for the too many values, you are trying to insert 5 values into a table with 4 columns. This could be a data problem or just a typo.
INSERT INTO PLC VALUES('4PLC','AEG PO 580','Burket','3','4')
should this be
INSERT INTO PLC VALUES('4PLC','AEG PO 580 Burket','3','4') -- no ',' between 580 and Burket
