Ques 2- I lost my job and have found another job. Will I be taxed at a higher rate because it is considered a second job?

No, if you have lost your job, then you are entitled to claim the tax-free threshold to reduce the amount of tax that is withheld from your pay from your new job. 

Second jobs usually have a higher amount of tax withheld from your pay because you already have another job from which you are earning income and are claiming the tax-free threshold. Withholding at a higher rate reduces the likelihood of you having a tax debt at the end of the income year.
