Can you retype your questions. Maybe a question per line. Too difficult to read or understand your post.

Use Google translate.

1)
No, you cannot, only for Non-Reserved.

Shikansen pass is called(named) "Flex", so Shikansen pass is "Flex-Pass(-teiki in JP)".

2)
Possible.

Also for Kodama top up discont ticket set exist.

However, top up 2480Y is correct but not sure basic Pass fare is 86950円 or not.

Maybe mostly same but it cannot calc by online(JR-Central/Tokai),
bc Conventional lines Pass distance limit is until 100km, Shizuoka is too far.
Making over 100km pass needs special approval.

In this case may be "two TOICA" IC cards pass. (for Nagoya-Maisaka, Maisaka-Shizuoka)
Maisaka is not Shinkansen stop stn, but pass validity is covered for Shikansen as parallel section.

Anyway, you should ask at JR ticket counter(Midori no madoguchi) or call, ASAP.

Perhaps Contact form may be enough,
but there is no guarantee that the reply will come definitely.

It's rather a trivial matter, but JR-Central has discontinued the nickname "Midori-no-madoguchi" in most stations.
I agree that you had better inquire of the company's staff.

Thanks.If I show student ID,Can I get Discount on 1 month shinkansen From JR Nagoya to Shizuoka ?
Can My child ride with Me (Age 4)Free of charge in shinkansen Non Reserved seats?

1)
A bit wrong, you have to paperwork(or use vending machine) at yr school first,
then that documet bring to JR stn, So, just showing yr school ID cannot buy it.
And Shinkansen pass for Student type called/named "Flex-PAL=フレックスパル".

BUT, do not know if yr school can use a school discount.

2)
Possible.

And,
BYW, how many times round per a month? Only for a month?
If will stay longer, if I were you, will think about move to Shizuoka city or not,
or in the moddle like Hamamatsu or easter cities Fukuroi, Iwata, Kakegawa...

Thanks so much.Do you think My Following clarification is correct:
First, I go to JR central station,And collect Student Commuter pass Form and Go to University's student office.And collect official stump of U at the back of Teikiken Form.Now I go to JR Nagoya with 93080円
For 1 month shinkansen フレックスパル pass.or pay 43830円 For Local train 1 month student pass. (2).Any child (age under 6)can take a seat in shinkansen Non Reserved seats Free of charge with paying adults.At weekend or After class Hour or New year Holiday or public Holiday,I want to travel.Because I have no Basic Knowledge,How Japan Looks Like.How they made their country after WW2.This is not part time job(arubaito)purpose.IF I live in Nagoya,I never go 185 km distance away and paying 93080円 on rail pass,to take baito in Shizuoka.This is For sightseeing purpose.
