Yes, it is.
The thousands digit is 4 left of the decimal point and the ones digit is the digit to the left of the decimal point. In a whole number the decimal point is not written and can be considered as "hiding" after the last digit - the ones digit.
Yes A whole number is even if its least significant digit is even. The least significant digit of a whole number is the digit in the "ones place". In other words, if the digit at the far right is 0, 2, 4, 6 or 8, the number is even.

The thousands place is the digit 4 left of the decimal point; in a whole number the decimal point is "hiding" after the ones digit. In 26195 the thousands digit is 6.
When rounding 2.68 to the nearest whole number, we look at the digit in the ones place, which is 8. Since 8 is greater than or equal to 5, we round up the ones place to the next higher digit, which is 3. Therefore, rounding 2.68 to the nearest whole number gives us 3.
There are infinitely many such - every tenth number after 2 ends in 2.
The tens place value is the second digit to the left of the decimal point. The decimal point is always to the right of the ones digit; in a whole number, the decimal point is "hiding" (not written) after the ones digit. In 3040 the tens digit is the 4.
Look at the digit after the ones digit - the tenths digit; if it is 5 or more round up, otherwise it is less than 5 so round down. The tenths digit (the one after the decimal point) is a 9 so round up: 986.91 → 987 to the nearest whole number.

It is the digit 7 that is in the ones or units place
A whole number has no decimal places, so you'll be rounding to the ones place. The digit after the 6 in the ones place is greater than 5, so the number 6 is rounded up to 7. Therefore, the nearest whole number is 987.
