Plural is a number, not a tense (e.g. the snail is singular number, the snails is plural number).
A tense is the time frame of a verb (e.g. I go is present tense, I went is past tense).
In English, the plural is usually formed by adding -s, or -es after vowels or sibilants, with a few irregulars (e.g. child/children, man/men, woman/women, ox/oxen, etc.) and some foreign plurals (fungus/fungi, criterion/criteria, etc.).
The word "rules" can be either a noun or a verb. As a noun, it's the plural form of rule. As a verb, it's the present tense, third person singular conjugation of rule.
No. As 'you' refers to either second person singular or plural noun, it takes a plural verb of 'to be'. As you want to refer to the past tense in your sentence, the plural verb of 'to be' in the past tense is 'were'. The correct sentence should be like this: You were not there.
