Let's do it with your hinge parts
You have to take some helper part. For this connection, in "Search" tab, find a bar part. I used Bar 3L (87994), but you can use longer too

Put it into the hinge point. It is better to paint it on unusual color, here I used dark pink, but the choice is yours
This is optional and does not change anything, but you can move it like that
Now select the bar
Then hold the ctrl button...
...and select the hinge top
Press R and rotate your camera. Now you can rotate the hinge top as you wish
You can select more parts or/and submodels if you need. All you need to remember is that helper part MUST be selected first, then other parts that will be rotated
