I upload the vector image, can I upload the same account photos and videos?

Read the Contributor help pages. Yes, you can upload all asset types to one account. In fact, you are NOT allowed to open up multiple accounts.

If you contribute different types of assets, you even need to upload those to the same account, as it is no more allowed to create different accounts. So the answer to your question is a clear yes, you can submit any types of assets that you can upload (i.e. that the system accepts). As long as you are following the rules as laid out in the manual for each asset type, there are no issues to be expected. And yes, your account will be safe, as long as you respect the contributor agreement and the terms and conditions. Check the documentation for this.
