Plugin or Plugins – Data Entry / Status?

I am new to WordPress.. Converting myself from Joomla to WordPress.

My question is that is there a plugin or plugins that can do any of these things:
1. When a client logs into their account on the site their own details of each campaign is on the site that they created so they can modify it, like start and end date and other various details.
2. Have a Data Entry page where they can select and enter in the campaign details and even upload images as they wish.
3. Maybe have a section in there for reports on how many people are signed up under them.

I hope this makes sense.
