It is short for: We would help ourselves and is correct. There are two possible meanings. It could be part of a second conditional idea. (If we were invited to,) we'd help ourselves. It could also be expressing a repeated action in the past. e.g. Growing up, mealtimes in our family were very informal - we'd help ourselves. It's not possible to know which meaning is intended without context.

It's in the conditional tense. A "results" clause like this is usually paired with another clause that states a condition: Even if no one else would help us, we'd help ourselves. It could also be a complete sentence if the condition is contained in a question: Q: What would you do if no one would help you? A: We'd help ourselves.

I don't think it is a tense. "Would" is a modal verb. All the modals take an infinitive and they never conjugate. There is no need to refer to a verb pattern that never conjugates as a tense. It makes little sense. If I were forced to call it a tense, I would call it past tense of "will" because, historically speaking, that is how "would" entered the English language. In Old English, the verb order would have been different: "We would ourselves to help", and once upon a time the modals were actual first-class verbs. Another meaning of "we would help ourselves" is as follows. Imagine you are at a banquet where there is a lot of food on the table. If you take your own food, rather than letting someone else put it on your plate for you, that is called "helping yourself".
