So if a day is 24 hours and there are 60 minutes in an hour and 60 seconds in a minute lets say I was to get $10 every second because theres 86400 seconds in 24 hour, lets do 86400 x 10 and see how much cash I get in one day by $10 every second

86400 seconds x $10 = $864,000

You would get $864,000 in one day if you were paid $10 every second.

Now if I was paid 1 million every full day, I would get 1 million just in my total

That's correct. If you were paid $1 million every full day (86400 seconds), your total earnings for that day would be $1 million.

Now heres the final question how much money would I have in year if I chose 1 million dollars every full day, and how much money would I have if I chose to get 10 dollars every full day (86400 seconds)

To calculate your earnings in a year:

For $1 million every full day,
$1 million x 365 days = $365 million

For $10 every second (which is $864,000 per day),
$864,000 x 365 days = $315,360,000

So, if you chose $1 million every full day, you would have $365 million in a year, and if you chose $10 every second, you would have $315,360,000 in a year.
