I own MacBook Air (early 2015) where the GPU and its memory reads as following:
Intel HD Graphics 6000 1536 MB
I think that the amount is a bit too high so I would rather decrease it to 1000 MB or something lower so I can benefit from higher RAM for applications.
Is there a possibility to do something like that?

You can't reduce the shared system memory. (See this question/answer on the Apple Support Forums)
Per EveryMac.com, the HD Graphics 6000 can allocate upto 1.5GB of system RAM. This is handled at the hardware level - some PC BIOSes allowed you to modify this value, but it's not common anymore and definitely not so with Apple.
So, to "free up" this RAM, you have two choices:
Since the first is not desireable and the second is impossible, if you absolutely need more memory, it's time to upgrade your MacBook to one with 16GB or more.
