Can I have multiple health insurance policies?

I currently have a high-deductible personal health insurance plan. I work as an engineer for a small company (under 10 employees) and we're finally getting a group policy. I'm worried that if I was serious injured/ill, I would be unable to work and my health insurance would end.

Can I keep my high-deductible personal plan (only costs $50/mo) so I know I always have health insurance even if I quit my job or am unable to work and still join the group plan so I have a much lower deductible?

consult this site, I found it while browsing the internet. It is an auto and health insurance company.

Some, but not all, insurance companies have a contractual clause that prohibits you from having multiple policies, and the ones that don't, will not "coordinate benefits". It's probably not going to be an an issue for you.
You are wise to keep your individual health plan, if you can afford it, but, unless you choose an HSA compatible plan through work, you can not continue to make non-taxable contributions to your HSA account.

Well, you can keep it, but YOU don't get to pick which one is primary. Usually, the costs outweigh the benefits.

You should talk to the agent that sold you the high deductible plan to look at the coverage limitations, to see if it's really going to "work" for you.

Sure , as long as you don't try and file a claim under both plans at the same time.
