CCleaner is not doing anything good. It's about the most benign (useless) cleaning app out there, but still not worth having. And that goes for any app that claims to speed up, clean or optimize your system. Do not use any of them.
Other than that, the problem is you only have 8 GB of RAM, which is being greatly overtaxed by having at least one more OS running in VMware, besides MS Office. Over 13 GB of data has been swapped out to the SSD in order to try and run everything you have going. That's a lot, and will easily result in the OS stalling on commands.
The RAM in your Mac cannot be upgraded, so you're stuck with 8 GB. Hate to say it, but your only solution is to purchase a much more capable computer so it can run everything you have going. Bare minimum, 16 GB RAM. And personally, I'd go for more.
