How to Substitute columns with sed

I have 2 txt files that read like this
12345;Mary;3;2;36
35248;Joe;5;10;2
42579;Ruth;4;5;8
And
2018 10 19;35248;;6;4.2
What I need, and have been unable do is update the first file with the second. When the 1st column of file 1 matches with the 2nd of file two, file one is supposed to add 1 to the 3rd column, 6 to the 4th and 4.2 to the 5th.
Desired output:
35248;Joe;6;16;6.2
I have tried using sed but it doesn't work. What I have at the moment is this:
if [ -e file2.txt ]; then
cat file2.txt | while read line; do
id=$(echo $line | cut -d';' -f2);
m=$(echo $line | cut -d';' -f5);
p=$(echo $line | cut -d';' -f4);
grep "$id" file1.txt | sed 's/
else
echo "No pending updates."
Thank you
