You can Install and use any number of SEO plugins at the same time, there are no restrictions technically. But in general it is recommended and better to have one plugin for each functionality, and SEO is no exception.
Actually there may be more disadvantages when you use multiple SEO plugins for a website at the same time. You need to make sure the plugins does not conflict with each other and there are certain things you need to watch out like,
- Make sure you have only one sitemap XML generated -because each SEO plugin tend to create one.
- Make sure you have the meta and description identical on each SEO plugin
To me using multiple SEO plugins at the same time will not add much value than a overhead for you and is not advisable or recommended.
