Sure, as long as they fit within a 5-foot cube. But keep in mind you can't move the illusion around.

Can I make an illusion of a rock in a five foot cube and hide in it?

Sure, if you can fit in a five-foot cube. Some larger characters might have difficulty with that, even crouched down.

Is an illusory sound only audible within a 5’ cube?  A visual illusion is visible outside the 5’ cube, so I would expect a sound would be audible from more than 5’ away. 

Would sunlight permeate through an illusion?

If you want it to, I suppose. There's no reason to assume it would by default.

It's audible as far away as it normally would be at whatever volume it is (which it says can be anything between a whisper and a scream). The section on auditory illusions does not mention 5' cubes at all, so that doesn't apply.

Well my DM hates me.  

Playing an illusionist that can use this as a bonus action.  

I create a 5x5 stone block I stand in. Since I am interacting with it, it becomes faint and I can see through it.  

That means anyone that is attacking me has the Heavily Obscured condition for their attack, on me so they are attacking me with disadvantage.   

Also because Heavily Obscured counts as Blinded, I have advantage on my attack rolls against them.  

I an also concealed so I can't be targeted by LOS spells.    

I'm not sure it's worth it, my DM is getting pissed because I do this every combat. 

I feel in this case, it would be reasonable for your DM to point out that since the enemies see you phasing through a stone block that they can discern it is an illusion, unless you are primarily hiding behind it acting as if it was real cover.

I do wonder if in the case of illusions that everyone can see such as Minor Illusion, if one person discern something is an illusion would that person's allies be able to also discern it is an illusion (they can yell "Hey, that stone block's an illusion!" or something) or would they need to make a separate Study action to tell?

They may know it’s an illusion, but they still can’t see the caster. If they do want to see the caster, they have to take the Study action. Its a good defensive strategy for illusionists, which is the only subclass that can cast it as a bonus action. 

And before we say it’s broken, it doesn’t stop AoEs from hitting the caster. A high attack bonus with disadvantage still has a good chance to hit the caster. The caster can’t cast a spell that turn and is hiding in an obvious spot. The illusionist can still cast a spell on the same turn, but is not misty stepping out of the combat area

With illusionists ability to cast this as a bonus action, it could work as a bonus action disengage. Cast minor illusion as a puff of smoke with the sound of “poof” on your square. You are now heavily obscured which will prevent adjacent targets from getting attack of opportunity on you when you run. 

Now before anyone says that’s broken (some DMs really hate illusions for no reason), the enemy sees the caster now, chases him with movement, and attacks with action. Also, only illusionist wizards get this tactiC, which is in essence just mimicking cunning action or step of the wind

Hating illusions is a sign of a lack of imagination.

I would just say you have total cover and cant be targeted directly.  If you walked into the block from behind it they would not even be alerted that it was an illusion.  The easy DM fix for this is just to charge up to the block and swing at it.  Yeah they are going to swing at disadvantage against you but they are going to hit the block and reveal the illusion now you are in melee range as a caster and let the pain begin.

I would say no if the shadow would go outside the 5ft cube. Anyone else have thoughts on sunlight permeating through illusions?
