David, "Used to" refers to past habits and states which were true in the past but are not true any more. It can be used with both action verbs and state verbs. "Would" describes repeated past actions, but not states. It can only be used with action verbs. For instance, I used to be illiterate when I was young, but I learned to read. CORRECT I would be illiterate when I was young, but I learned to read. INCORRECT because "to be" is a stative verb. I used to climb trees when I was young. CORRECT I would climb trees when I was young. CORRECT because "to climb" is an action verb. Now that you know the rules, you should be able to find the answers all by yourself. :)

I can see, that all of the sentences are fragmented. It is all broken. So, I cannot detect what are you pointing out. If it is, present, past or future. ^^, "WOULD" is an auxiliary verb, a modal auxiliary verb. We use would mainly to: talk about the past talk about the future in the past express the conditional mood "USED" We use 'used to' for something that happened regularly in the past but no longer happens. We also use it for something that was true but no longer is. We use 'to be used to doing' to say that something is normal, not unusual. We use 'to get used to doing' to talk about the process of something becoming normal for us. :) hope you understand the differences.
