1. yes
2. yes
3. no
The degree of a polynom is the maximum, eh, number of variables multiplied with each other, counting powers as multiple multiplication. Or to say it another way around, the maximum sum of powers of variables in a term. For example, the degree of a^4 is 4, the degree of a^2b^3 is 5, the degree of abc + d^2 is 3, the degree of abcd + e^7 is 7.
4. no
Terms are the bits that you add (or subtract) together. Things that you multiply with each other are factors.
5. no
In the standard form, you sort the terms in descending order of power. Highest power first, lowest last.
