Yes without youre permission
No, not legally.
No. if you have (and if questioned on it, can ultimately prove you had) the person's permission to sign their name it is not forgery. Two elements must be present to form a crime. (1) a criminal act done with (2) a criminal intent. Take either one of thse elements away and you do not have the legal basis for a crime. Therefore, if you sign someone's name with their permission there is no intent. However this is not to say that some banks or financial institutions, etc. will allow you to do this, they may require you to show a legal 'Power of Attorney.'
