One Scrum team with all different projects

Do you feel they're actually a team or more of a group of individuals at that point? 

Scrum is product focused. The very first line in the Scrum Guide is:

Scrum is a framework for developing, delivering, and sustaining complex products. 

It also says that:

Scrum Teams deliver products iteratively and incrementally, maximizing opportunities for feedback. 

If you have one team that is truly supporting multiple products, it is likely going to be hard to take advantage of some of the features of Scrum. Perhaps you can consider that, although maybe pieces of Scrum are useful, other aspects may not be and Scrum, as a whole, may not be the best fit for your work.

I have a scenario that I have a scrum team of 6 people, but all are working on different projects

Does the team have a Product Owner who can agree a coherent Sprint Goal with the team, one which allows them to work together instead of on different initiatives?

 If yes then how I can maintain their scrum board?

Fahad, why do you believe it is your responsibility to maintain the team's board?

Okay thank you All for your replies, There are informative and learning thing for me. 

Can you please help me with this scenario to be exact. 

Actually I am the project manager of a team. You can say a group of 6 individuals not a team, because they all are working of different projects & technologies. They are not connected with each other in a direct way.

Now I have to manage/map them of Jira, so I can track their work, things on which they are working their timelines etc. You can say project progress of every one of them.

Can I put this case under agile, because we are working on each project in an iterative approach? if yes then which board is best for this ?

As you guys answer above if its not scrum as 'scrum is for complex projects' 

then Can we put it under Kanban Board?? or something you can suggest best.
